Das Ziel der Arbeit bestand darin, die lokalen und globalen mechanischen Beanspruchungsparameter in einem Rührkesselbioreaktor mit Hilfe der numerischen Strömungssimulation (CFD) nachzubilden und die Ergebnisse mit experimentellen Daten der Pellet-kultivierung bzgl. Fluiddynamik und Rheolgie des rekombinanten Stammes A. niger SKAn1015 zu validieren. Ausgehend von der einphasigen Strömungssimulation eines 2L-Bioreaktors werden zunächst Simultionsdaten über Strömungsgeschwindigkeit und mechanische Beanspruchung diskutiert. Aßerdem erfolgt eine Validierung der einphasigen Simulationsdaten mit der Particle Image Velocimetry. In weiteren Untersuchungen wird die Strömungssimulation auch auf nicht-newtonsche Flüssigkeiten, so wie sie bei der Kultivierung filamentöser Pilze üblicherweise auftreten, mit dem Ostwald - de Waele-Ansatz erweitert und die mechanische Beanspruchung in Abhängigkeit zu den rheologischen Prozessparametern korreliert. Die Untersuchung des Einflusses unterschiedlicher Rührergeometrien auf die Strömungsfelder und die mechanische Beanspruchung mittels CFD bildet den Abschluss, so dass die Auswahl eines geeigneten Rührers für den Kultivierungsprozess mit schesensitiven biologischen Systemen eindeutig getroffen wird. Die Arbeit validiert die numerische Strömungssimulation in einem Bioreaktor mit experimentell gnerierten biologischen und fluiddynamischen Prozessdaten und gibt praktische Hinweise darüber, wie biotechnologische Prozesse mit filamentösen Mikroorganismen hinsichtlich der Minimierung der mechanischen Beanspruchung zu betreiben sind.

Covering the important task of the scale-up of processes from the laboratory to the production scale, this easily comprehensible and transparent book is divided into two sections. The first part details the theoretical principles, introducing the subject for readers without a profound prior knowledge of mathematics. It discusses the fundamentals of dimensional analysis, the treatment of temperature-dependent and rheological material values and scale-up where model systems or not available or only partly similar. All this is illustrated by 20 real-world examples, while 25 exercises plus solutions new to this edition practice and monitor learning. The second part presents the individual basic operations and covers the fields of mechanical, thermal, and chemical process engineering with respect to dimensional analysis and scale-up. The rules for scale-up are given and discussed for each operation. Other additions to this second edition are dimensional analysis of pelleting processes, and a historical overview of dimensional analysis and modeling, while all the chapters have been updated to take the latest literature into account. Written by a specialist with more than 40 years of experience in the industry, this book is specifically aimed at students as well as practicing engineers, chemists and process engineers already working in the field.

Computational fluid dynamics, CFD, has become an indispensable tool for many engineers. This book gives an introduction to CFD simulations of turbulence, mixing, reaction, combustion and multiphase flows. The emphasis on understanding the physics of these flows helps the engineer to select appropriate models to obtain reliable simulations. Besides presenting the equations involved, the basics and limitations of the models are explained and discussed. The book combined with tutorials, project and power-point lecture notes (all available for download) forms a complete course. The reader is given hands-on experience of drawing, meshing and simulation. The tutorials cover flow and reactions inside a porous catalyst, combustion in turbulent non-premixed flow, and multiphase simulation of evaporation spray respectively. The project deals with design of an industrial-scale selective catalytic reduction process and allows the reader to explore various design improvements and apply best practice guidelines in the CFD simulations.
