Multiphase processes


Transport processes in multiphase flows 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 behaviour in systems which often show complex mutual interactions. In addition, the experimental investigations in liquid/liquid systems, phenomena such as drop breakage, drop coalescence or interfacial instabilities are also investigated in simplified systems. Optical in situ measurements provide local information pertaining to the volume fraction as well as drop-size distribution in such systems.

In recent years, fluid dynamics simulation tools (CFD) have 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 both commercial as well as non-commercial CFD codes for research, development and technology optimisation.
