Berend van Wachem

Berend van Wachem obtained his MSc and PhD degree at Delft University of Technology on the modeling of dense gas-solid flows. After spending a number of years as a lecturer in Sweden, he joined the Department of Mechanical Engineering of Imperial College London in 2008.

Research

Berend van Wachem works on research projects involving multiphase flow modeling, ranging from understanding the behaviour of turbulence on individual particles and droplets, to the large-scale modelling of gas-solid and gas-liquid flows. He is one of the editors of the "Best Practice Guidelines for Computational Fluid Dynamics of Dispersed Multiphase Flows", has contributed to the "Multiphase Flow Handbook", and has published a number of review papers on multiphase flow modeling and understanding.
