After his MSc in Hydraulic Engineering at Delft University of Technology, Bas accepted a PhD position at the Dredging Group in Delft. His work combines a numerical and experimental approach to describe spillage when cutting rock with cutter suction dredges. The experiments are designed to validate the numerical model. He therefore designed a simplified cutter to measure the fluid velocities and particle positions. For the model, he implemented a method for modelling big chips of rock in a rotating cutter using relatively coarse grids, allowing the model to simulate rock trajectories in the cutter with decent computation times.
