Transport phenomena in multiphase processes play a major role in many industrial applications and scientific investigations. One of the most interesting aspects is the study of mass transfer and hydrodynamic behavior in gas/liquid and liquid/liquid systems which often show complex mutual interactions. Beside simulations experimental investigations in multiphase systems were carried out to study phenomena such as drop breakage, drop coalescence or interfacial instabilities. Optical in situ measurements provide local information pertaining to the volume fraction as well as drop-size distribution in such systems.

In recent years, CFD has played an important role in unravelling complex multi-phase transport phenomena in close co-ordination with experimental results. Our group is involved in the application of CD-adapco’s codes for research, development, technology optimization and teaching since the 1990s. A first milestone in the use of CD-adapco’s products was the successful simulation of concentration induced Marangoni convection in a single drop: Mass as well as momentum transfer could be predicted very well and the simulations helped significantly in understanding the process. Within the cluster of excellence Unicat (Unifying Concepts in Catalysis), STAR-CCM+ is used successfully to simulate detailed heterogeneous reactions in spatially resolved fixed bed reactors. But also mixing problems in stirred tank reactors for the prediction of drop size distribution or for a better understanding of the behavior of non-newtonian fluids are investigated at the chair. Beside research, STAR-CCM+ is also used in a lecture ‘CFD for chemical and process engineering’.

This lecture is a kind of CFD crash course with a focus on applications and not on the numerical recipes. STAR-CCM+ enables the students to setup and solve complex problems within two weeks.
