Gedenken an Dr.-Ing. Michael Wolff

Am 18. August 2022 verstarb plötzlich und unerwartet und viel zu früh Dr.-Ing. Michael Wolff im Alter von 38 Jahren.

Wir trauern um einen ehemaligen Mitarbeiter,
der von 11/2009 bis 10/2015 am Institut für Feststoffverfahrenstechnik und Partikeltechnologie der Technischen Universität Hamburg Doktorand war.

Ganz besonders ist, dass er als Physiker mit einem 1,0-Abschluss der Universität Hamburg zu uns an die Technische Universität kam und unbedingt im Bereich der Ingenieurwissenschaften am Institut promovieren wollte. Das hat mich tief beeindruckt und natürlich war ich glücklich, solch einen exzellenten, ehrgeizigen Kandidaten als Doktoranden zu bekommen. Er hat in all den Jahren am Institut viele interessante Fragestellungen zur sogenannten Strahlschichttechnologie - speziell zur Erzeugung hochgefüllter Keramik-Polymer-Komposite - sehr erfolgreich bearbeitet und seine Dissertation mit dem Prädikat „sehr gut“ abgeschlossen. Gemeinsam haben wir auch ein Weltpatent erarbeitet, was er als Doktorand in großer Akribie entwickelt hat. Seine Vorarbeiten im Landesexzellenzcluster haben maßgeblich dazu beigetragen, dass wir seit der ersten Förderperiode Mitglied des DFG-Sonderforschungsbereiches 986 sind. Er gehörte zur ersten Doktorandenkohorte und hat insbesondere die Kooperation mit Prof. Schneider vom Institut für Technische Hochleistungskeramik begonnen.

Seit seiner Promotion arbeitete er bei der Lindauer DORNIER GmbH. Auch dort wurde er von seinen Kollegen und der Geschäftsführung sehr wertgeschätzt, sowohl für seine persönlichen Qualitäten als auch für sein fachliches und wissenschaftliches Arbeiten.

Das Institut verliert mit ihm einen äußerst liebenswerten Menschen und Alumni.

Alle Mitarbeiter des Instituts werden ihm stets ein ehrendes Gedenken bewahren.

In großer Trauer

Trilateral project with Fraunhofer IFF and Pergande GmbH

Our trilateral project "Development of an intelligent Digital Twin for the prediction and control of the fluidized bed spray granulation process conditions by means of transient flowsheet simulation" is selected as one of five projects which are funded by the German Research Foundation (DFG) and the Fraunhofer Gesellschaft.

Project coordination:
Professor Dr.-Ing. Stefan Heinrich, TU Hamburg,
Professor Dr.-Ing. Przemyslaw Komarnicki Ph.D., Fraunhofer Institute für Factory Operation and Automation IFF, Magdeburg

Partner: IPT-Pergande GmbH, Weißandt-Gölzau

The aim of the work is the development of an intelligent Digital Twin using the example of the fluidized bed spray granulation process. With faster than real-time simulations the Digital Twin reproduces the state of the physical plant and predicts its future behavior, enabling reliable control of the process. Underlying models will be developed with help of experimental data. The resulting model will then be implemented in the flowsheet simulation software Dyssol which has been developed during the DFG predecessor project (SPP 1679). The implementation into the process control system is conducted at the industrial partner, the company Pergande Group. Besides the operation of lab-scale plants, the transferability to larger plants will be demonstrated.

Dr. Rachel Smith of the Department of Chemical and Biological Engineering at the University of Sheffield honored our Institute with a visit on the 21. and 22. of November. She held a talk titled "Rate Processes in Particle and Powder Technology" as part of the SPP1679 seminar. The abstract reads as follows:

Particle and powder processing plays an essential role in a wide range of industries, spanning foods, pharmaceuticals, consumer products, additive manufacturing, specialty chemicals, minerals processing, and many more. Despite the importance of powders in manufacturing, many of the unit operations remain difficult to design and predict, and require extensive experimentation and trial and error for scale up. It is clear that better fundamental understanding is required. 

My research focuses on understanding particle-particle and particle-fluid interactions, using these interactions to develop mechanistic understanding of powder processes, and identifying and quantifying the rate processes that are occurring. In this talk, I will discuss some of my research on the rate processes of three different methods of powder processing: powder coating, granulation, and spherical agglomeration.

Lecture by Prof. Ravendra Singh

Prof. Ravendra Singh of the Particle Systems Lab at Rutgers University will visit our institute and hold a lecture entitled

"Advanced modelling and control of continuous pharmaceutical manufacturing process"

on the 16.07.2018, 14:00 in Room N009. 

Abstract of the talk

Currently, pharmaceutical industries are going under paradigm shift from traditional batch to novel continuous manufacturing. Such a novel continuous plant has been built at C-SOPS which is being adapted by several pharmaceutical companies. In this work, the continuous pharmaceutical manufacturing (CPM) pilot-plant has been further modernized via utilizing process system engineering methods and tools. Process model, real time monitoring, advanced model predictive control (MPC) system, data management system and material tracing system are critical components of modernized CPM pilot-plant. A validated process model has been developed for in-silico studies and virtual experimentations. A process model plays a very important role to design, evaluate and tune the control system. The developed control system has been then implemented in to the continuous tablet manufacturing pilot-plant for practical demonstration. Moreover, a RTD (residence time distribution) based control system has been developed for automatic real time rejection of tablets which are not complying with regulatory expectations on drug concertation.

Center for Biobased Solutions (CBBS) launched

The Center for Biobased Solution (CBBS) has launched - with SPE as a founding member. 

The center's declared mission is as follows:

The challenges that our society is facing are enormous including climate change, growing population, limited resources, decline of crude oil, energy supply, nutrition, health and mobility. The development of intelligent bioeconomy concepts will play a pivotal role for the future developments, which are based on the more efficient use of the biomass of our planet aiming at the production of new biobased materials, pharmaceuticals, biopolymers and chemicals for various applications. Digitalization will have a great impact on this transformation process as well as advanced training and qualification programmes. The successful transition from crude oil era to bioconomy will be dependent on the efficient conversion of biomass by reliable and stable catalytic processes. Specific adapted technologies of mechanical, chemical and biotechnological nature are needed and interdisciplinary connected. In addition, other disciplines including metagenomics, transcriptomics, logistics and social aspects are essential.

Visit and lecture by Prof. Stefan Pirker of JKU Linz on April 3rd

Prof. Dr. Stefan Pirker, Head of the Department of Particulate Flow Modelling from the Johannes Kepler-Universität Linz (JKU) will visit our institute on April 3 & 4 2018. 

His research interests are numerical modelling of particulate flows with special emphasis on multi-scale model synthesis. This involves (i) embedded co-simulations and sub-grid models, (ii) hybrid Eulerian and Lagrangian simulations as well as (iii) recurrence models for efficient time extrapolation of full CFD simulations. The outcome of his research group has been disseminated by open-source codes (CFDEMcoupling, LIGGGHTS) and by to date more than 150 publications in scientific journals and refereed conference proceedings.

He will give a lecture titled "Can we bridge between recurrence CFD (rCFD) and process control?" on April 3rd 14:00 in Room H0.09

Abstract

Recurrence CFD (rCFD) aims at an efficient representation of long-term processes (e.g. heating, chemical conversion) which slowly evolve on highly-dynamic pseudo-periodic flow fields. In such cases classical CFD simulations fail due to excess computational cost associated with the resolution of the governing flow fields.

In the framework of rCFD, short-term full CFD simulation deliver recurrence databases of the governing flow at different operating conditions. Based on statistical reasoning, rCFD then exploits these databases in order to either develop (i) generic flow fields or (ii) generic transport fields, which subsequently serve as basis for the long-term process under consideration. We further present an interpolation methodology for the representation of unsteadily varying operating conditions (i.e. between existing recurrence databases).

In applying rCFD to a set of single-phase and multiphase flows, we experienced a computational speed-up of two (flow based rCFD) to four (transport based rCFD) orders of magnitude. In many cases this dramatic speed-up allows for faster-than- realtime simulations, although we didn’t reduce the resolution of the original full CFD simulation.

Finally, we explore the possibility of incorporating such real-time rCFD simulations into process monitoring and control.

Visit and Lecture by Prof. Ramachandran of Rutgers

Ass.-Prof. Rohit Ramachandran of Rutgers State University of New Jersey will be visiting our institute from 19-29.03.2018. He will hold a guest lecture titled:

Kaum eine Berufsgruppe ist hierzulande so gefragt wie Ingenieure, Informatiker, Naturwissenschaftler & Co. „In diesem praxisorientierten Projekt wecken Experimente in den Schulen zunächst die Neugier, bevor die Kinder hautnah miterleben, wie an der TUHH an den gleichen Themen geforscht wird", erklärt Gesine Liese, Leiterin des Projekts Kinderforscher an der TUHH, das Konzept von "Experimentieren und Forscher“.

So lernten etwa Dritt- und Viertklässler der Schule „In der Alten Forst“ kürzlich, was Popcorn mit Partikeltechnologie zu tun hat. Dabei staunten sie nicht schlecht, als sie eine von TUHH-Studenten gebaute Maschine in Aktion sahen, die veranschaulichte, was heiße Luft mit Maiskörner macht. Nun wissen die Nachwuchsforscher: Durch heiße Luftströmung verdampft das im getrockneten Maiskorn enthaltene Wasser, das sich hierbei ausdehnt und aufplatzt. Dadurch werden die Maiskornpartikel deutlich größer und haben gleichzeitig eine geringere Dichte als die verschlossenen Körner.

Insgesamt haben am aktuellen Kurs rund 150 Dritt- und Viertklässler aus drei Bundesländern teilgenommen. Ermöglicht wird dies durch die Unterstützung der Beratungsstelle Besondere Begabungen am Landesinstitut für Lehrerbildung und Schulentwicklung Hamburg sowie der Firma MERCK.

TUHH-Doktorand mit Best Poster-Award ausgezeichnet

Im Rahmen des World Congress of Chemical Engineering WCCE10, der Welttagung der Verfahrenstechnik, ist der Doktorand Eugen Diez der Technischen Universität Hamburg (TUHH) mit dem Best Post Award geehrt worden. Mit seinem Beitrag „Spray granulation in a multi-staged continuous fluidized bed: Influencing the product properties and particle transport in a horizontal fluidized bed“ wurde seine Arbeit aus insgesamt 62 Poster-Beiträgen ausgewählt. Das ausgezeichnete Projekt wird am TUHH-Institut für Feststoffverfahrenstechnik und Partikeltechnologie von Prof. Heinrich betreut. 

Wie wird Waschpulver so fein körnig? Wie können Arzneimittel den Wirkstoff noch gezielter freisetzen? Warum funktioniert die Babywindel so gut? Warum verklebt Lebensmittelpulver nicht? Wie kann man den Einsatz von Dünge- und Pflanzenschutzmitteln drastisch reduzieren? Im Projekt wird der Fragestellung nachgegangen wie hochwertige, frei fließende und staubarme körnige Feststoffe mit verbesserten Gebrauchseigenschaften energie- und umweltschonend hergestellt werden können, die im täglichen Leben oder in zahlreichen Industrien Anwendung finden. Zur Lösung dieser Aufgabe wird ein skalenübergreifender Ansatz verfolgt, der experimentelle Untersuchungen mit unterschiedlichen Modellierungsansätzen und einer systemdynamischen Analyse einer kontinuierlichen Wirbelschicht-Sprühgranulation kombiniert.

Die prämierte Arbeit entstand innerhalb des DFG-Schwerpunktprogrammes 1679 im Rahmen gemeinsamer Forschungen mit dem Lehrstuhl für Thermische Verfahrenstechnik (Prof. Tsotsas) sowie dem Lehrstuhl für Automatisierungstechnik / Modellbildung (Prof. Kienle) der Universität Magdeburg.

Maksym Dosta ist Juniorprofessor für Mehrskalensimulation von Feststoffsystemen an der TUHH

Sand, Waschmittel, Tabletten: Pulver sind überall. Mehr als die Hälfte aller Produkte in der chemischen oder pharmazeutischen Industrie werden aus Feststoffpulvern hergestellt. Das erfordert komplizierte Prozesse, die beschrieben und optimieren werden wollen. Dabei spielt die Modellierung eine große Rolle, das Forschungsgebiet von Dr.-Ing. Maksym Dosta. Der 32-Jährige ist seit dem 1. Februar 2016 neuer Juniorprofessur für Mehrskalensimulation von Feststoffsystemen am Institut für Feststoffverfahrenstechnik und Partikeltechnologie der Technischen Universität Hamburg (TUHH). Die Juniorprofessur am Exzellenzkolleg der TUHH wurde in Kooperation mit der Firma Glatt Ingenieurtechnik GmbH eingerichtet. Sie ist eine der größten Hersteller von Wirbelschichtanlagen zur Behandlung von Partikeln aus den Bereichen Pharma-, Lebens- und Futtermittel sowie Feinchemie.

Die Herausforderung, die sich den Forschern bei der Prozesssimulation stellt: Sie können zwar die Dynamiken beschreiben, die sich zwischen zwei einzelnen Körnern auf der Mikroskala abspielen. Doch von diesen Körnern und Reaktionen gibt es mitunter Billionen, eine Modellierung des ganzheitlichen Prozesses unter Berücksichtigung jedes einzelnen Partikels ist unmöglich. „Man braucht also eine Art Übergang von der Mikromechanik zur makroskopischen Ebene“, beschreibt Maksym Dosta. Bei Mehrskalensimulationen von Feststoffsystemen handelt sich um eben diese Verbindung.

Dr.-Ing. Maksym Dosta kommt ursprünglich aus der Programmierung. Der gebürtige Ukrainer studierte Rechentechnik an der Technischen Universität in Donezk, bevor er 2006 ans Max-Planck-Institut für Dynamik komplexer technischer Systeme in Magdeburg ging. 2008 wechselte Dosta an die TUHH, um im Bereich der Feststoffverfahrenstechnik promovierte. Wie es nun zu dem Umschwung kam? „Die Modellierung von Feststoffprozessen ist sehr kompliziert, man muss viel mehr Parameter berücksichtigen, als zum Beispiel bei Fluidprozessen. Das hat meinen Ehrgeiz geweckt“, sagt der frisch berufene Juniorprofessor. Dosta freut sich auf die fachübergreifende Zusammenarbeit mit Kolleginnen und Kollegen der TUHH und will am Exzellenzkolleg eine Forschungsgruppe zu seinem Thema aufbauen.

Die Juniorprofessur ist im Rahmen des Exzellenzkollegs angesiedelt. Das in 2014 gegründete Exzellenzkolleg weist ein neues Forschungs- und Finanzierungskonzept auf. In Kooperation mit der Wirtschaft werden sechs neue Juniorprofessuren eingerichtet. Ziel ist es, gemeinsam nachhaltige Innovationen zu schaffen, die Wissenschaft und Wirtschaft in Hamburg gleichermaßen wettbewerbsfähig halten.

Workshop on DEM contact models and the simulation of multiphase flows

DECHEMA-Preis an Stefan Heinrich von der TUHH

Der DECHEMA-Preis 2015 geht an Professor Dr.-Ing. Stefan Heinrich von der Technischen Universität Hamburg (TUHH). Der DECHEMA-Preis ist mit 20.000 Euro dotiert und wird jährlich von der Gesellschaft für Chemische Technik und Biotechnologie e.V. (DECHEMA) für herausragende Forschungsarbeiten, die die Technische Chemie, die Verfahrenstechnik, die Biotechnologie und das Chemische Apparatewesen betreffen, verliehen. Heinrich wird für seine wegweisenden experimentellen und theoretischen Arbeiten zur Formulierung von Partikeln durch Wirbelschichtgranulation ausgezeichnet. Mit diesen Methoden können Partikel mit bestimmten Eigenschaften gezielt hergestellt werden, die in so unterschiedlichen Branchen wie der Pharma- und Lebensmittelindustrie, in der Biotechnologie, Keramik und bei Batteriematerialien zum Einsatz kommen.

Die Prozesse, die sich in der Wirbelschicht abspielen, sind außerordentlich komplex: Partikel stoßen zusammen, es kommt zur Befeuchtung, Trocknung und Filmbildung, Partikel brechen. Um Partikel mit gezielter Zusammensetzung, Schichtaufbau, Größe und Geometrie herzustellen, ist ein sehr gutes Verständnis dieser Prozesse notwendig. Heinrich beschäftigt sich mit der Analyse ebenso wie mit der Simulation der Vorgänge in der Wirbelschicht und hat neue Verfahren entwickelt, die eine gezielte Vorhersage über die Zusammensetzung und den Aufbau von Partikeln erlauben.

Stefan Heinrich, geboren 1971, studierte Verfahrenstechnik/Thermischer Maschinenbau an der Otto-von-Guericke-Universität Magdeburg. Nach seiner Habilitation übernahm er dort 2002 eine Juniorprofessur. Seit 2008 ist er Professor und Leiter des Instituts für Feststoffverfahrenstechnik und Partikeltechnologie der TUHH. Für seine Arbeiten erhielt er zahlreiche Auszeichnungen, darunter 2004 den VDI-Ehrenring, den Ingenieurpreis 2005 des Landes Sachsen-Anhalt für „Innovative Ingenieurleistungen zur Energieanwendung“, den „Otto – SWM Wirtschaftspreis 2005 für die Entwicklung des Softwareprodukts FBSim und den Forschungspreis des Landes Sachsen-Anhalt für Angewandte Forschung 2006.

Der DECHEMA-Preis gilt als wichtigster Preis der Verfahrenstechnik in Deutschland und ist mit einer Goldmedaille und 20.000 Euro dotiert. Die Preisverleihung findet am 1. Juni 2016 in Frankfurt/Main im DECHEMA-Haus statt.

Der Beitrag von Eduard Eichner entstand im Rahmen einer Kooperation mit dem TUHH-Institut für Keramische Hochleistungswerkstoffe, unter der Leitung von Professor Gerold Schneider, innerhalb des SFB 986 “Maßgeschneiderte Keramische Hochleistungswerkstoffe”. Sie widmet sich der Möglichkeit, mittels eines neuartigen Beschichtungsverfahrens in einer Strahlschicht hierarchisch strukturierte Keramik-Polymer-Kompositpartikel bzw. Bauteile herzustellen, die aufgrund ihrer speziellen Struktur eine besondere Festigkeit und Bruchzähigkeit besitzen. Diese speziellen Eigenschaften machen sie für technische Anwendungen interessant.

Anna Porowska hat in einem gemeinsamen Forschungsprojekt mit der Firma Nestlé den komplexen Entstehungs- und Transportprozess der Proteinverkapselung von Partikeln während der Sprühtrocknung analysiert und mit mathematischen Methoden und neuartigen Experimenten zugänglich gemacht. Ihre Ergebnisse werden bereits von Nestlé angewendet und helfen, die Auslegung derartiger Multikomponenten-Prozesse sicherer und besser vorhersagbar zu gestalten.

Der alle 2 Jahre stattfindende “International Granulation Workshop” ist die größte Fachtagung auf dem Gebiet der Granulation, Agglomeration, Beschichtung und Verkapselung von Partikeln und Feststoffen im Bereich der pharmazeutischen, chemischen, keramischen, biotechnologischen und Lebensmittelindustrie.

Scientists X-ray Chocolate

Study shows ways to reduce unwelcome whitish fat bloom

In order to study the migration of fats, the researchers also placed a few drops of sunflower oil on each of their samples and observed what happened. “First of all, wetting takes place within seconds. The oil penetrates very quickly into even the smallest pores, probably through capillary action,” Reinke describes their observations. Secondly, the liquid fat alters the internal structure of the chocolate. “Over a period of hours, the liquid fat dissolves additional crystalline lipid structures, which makes the entire structure of the chocolate softer. This in turn increases the migration of lipids.”

The dynamics of the development of fat bloom have so far been unknown, so that this study adds to the findings of previous experiments on the crystalline structure as one major factor influencing fat bloom. “For the first time, we have been able to track in detail the dynamic mechanisms that lead to the creation of fat bloom,” explains DESY scientist Dr. Stephan Roth, head of the P03 beamline at PETRA III, at which the experiments were conducted. “The method used is known as small-angle X-ray scattering and is precisely adapted to real-time investigations of this kind, and to observing the structural changes caused by the moving lipids. The joint study has supplied important information as to how we can study structural changes in such ‘everyday’ multi-component systems.”

The observations allow the food industry to develop concrete approaches for reducing fat bloom. “One consequence might, for example, be to reduce the porosity of the chocolate during manufacture, so that the fat migrates more slowly,” explains Reinke. “Another approach is to limit the amount of fat that is present in a liquid form by storing the product in cool, but not too cold, conditions. 18 degrees Celsius is ideal.” Chocolate is very sensitive to fluctuations in temperature. “Just a few degrees make a big difference,” Reinke notes. “At 5 degrees, basically, all cocoa butter is solid; and above about 36 degrees everything is liquid.” On top of this, the type of crystals in the chocolate plays an important role. “Cocoa butter crystallises in six different crystal forms,” explains Reinke. “The amount of fluid also depends on the form of the crystals.” Manufacturers can also limit fat bloom by controlling crystallisation.

“The experiments that have been conducted allow us as manufacturers of quality chocolate to draw conclusions concerning the root causes of lipid migration leading to blooming,” points out Palzer. “These findings, which we obtained in collaboration with the Hamburg University of Technology and the team at DESY using the latest analytical technologies, provide a solid foundation for developing suitable methods for avoiding one of the most important quality defects in the food industry.”

Deutsches Elektronen-Synchrotron DESY is the leading German accelerator centre and one of the leading in the world. DESY is a member of the Helmholtz Association and receives its funding from the German Federal Ministry of Education and Research (BMBF) (90 per cent) and the German federal states of Hamburg and Brandenburg (10 per cent). At its locations in Hamburg and Zeuthen near Berlin, DESY develops, builds and operates large particle accelerators, and uses them to investigate the structure of matter. DESY’s combination of photon science and particle physics is unique in Europe.
