The division of Process Technology/Chemical Engineering (VT) is part of the faculty of Production Technology at the University of Bremen. The staff comprises a number of about 35 researchers mostly process engineers but also chemists and physicists. Basic research and development activities of the division cover experimental, analytical and numerical work in various areas in the field of chemical engineering and powder technology. Four departments on the following topics have been established:
In the Department of Atomization and Coatings Technology (headed by apl. Prof. Dr.-Ing. G. Schulte) the main research work focuses on the atomization behaviour of several process fluids disintegrated by different types of atomizers. Basic investigations on the atomization process are carried out in application-orientated environments with practical relevance (e.g. spray drying, paint spray, spray forming, etc.) by means of sophisticated laser techniques (e.g. Laser Light Sheeting - LLS, Diffraction Size Measurement - DSM, Phase-Doppler Anemometry - PDA, etc) and high speed CCD-cameras.
The research activities in the Department of Multiphase Flow, Heat and Mass Transfer (headed by Priv.-Doz. Dr.-Ing. U. Fritsching) focus on multiphase flow problems including momentum, heat and mass transfer processes in various applications of liquid atomization (Newtonian-and non-Newtonian-process fluids, suspensions or molten metals. For the numerical simulation of multiphase flows commercial and self developed CFD-codes are used and enhanced, based on: - Euler / Euler simulation for two-phase flow, - Euler / Lagrange simulation for two-phase flow, - interaction of individual droplet/particles with fluid structures, - phase change modelling.
