After the successful defence of his PhD thesis entitled ‘Gas-liquid flow with drag reducers’ in 1983 Peter Hamersma joined Shell Research. After a short period in industry he returned as associate professor in Chemical Engineering and at the University of Amsterdam, where he worked on several research projects in the field of multiphase flow systems and turbulent pipe flow. In 1994 had a sabbatical at Institut Français du Pétrole (Solaize / France) where he worked on the hydrodynamics and dispersion in fixed-bed reactors. From 1995 till 2002 he was as course director responsible for BSc and MSc programs at the University of Amsterdam in the field of chemistry, chemical engineering and earth sciences and part-time director of the international school of science. In 2002 he joined Delft University of Technology as course director of BSc and MSc programs in the field of Chemical Engineering.
From spring 2008 he works part-time in research and has started two projects:1) mass transfer in static mixers to investigate how mass transfer can be enhanced under dynamic conditions and/or using different geometries and 2) on three-phase slurry reactors to investigate and develop new modes of operation to enhance the transfer processes involved in such systems.
