About Me

I am a PhD student that started with my research on bidirectional turbines for thermoacoustic engines in 2015. Before this I did my Bachelor and Master studies at the University of Twente as well. During the Master period I've done four months of research at Imperial College London on the subject of a two-phase thermofluidic prime-mover. I finished my Master with research on jet pumps for thermoacoustic engines.

My research is on the utilization of a bidirectional turbine for thermoacoustic engines. A bidirectional turbine is a specific type of turbine that rotates in the same angular direction, independent of the incoming axial flow. This research focuses on converting acoustic power, induced by the thermoacoustic effect from low-grade heat, into electricity.
