Martin Korevaar is a researcher on the drinking water treatment team. He models processes in water purification so that they can be better understood and optimised. For example, he works on Computational Fluid Dynamics (CFD) studies on (rinsing) quick filters, as well as on non-flow related research such as the development of models to study the absorption behaviour of (carbon) filters. Martin partially developed these skills during his master’s degree programme and PhD in which he developed numerical models to describe various types of physics. In addition to developing and simulating with CFD, he expressly focused on simulating two-stage flows (gas-solid).
