Dr. Bauwens' research interests include:
Hydrogen Safety. We are a member of the International Association for Hydrogen Safety HySafe, and also of the H2Can network of excellence, both of which focus on the safety of hydrogen as an automotive energy carrier. Tthe International Association HySafe came out of the European network, funded under the Sixth Framework Programme, coordinated by FZK (Research Center Karlsruhe, now KIT Nord). Members included the French Nuclear Energy Commission (CEA), Det Norsk Veritas, Air Liquide, Volvo, BMW, HSL, and a number of universities, research centers and corporations.
We focus in particular on the risks associated with detonation waves. Our focus is on the relationship betweenchain-branching chemistry and the structure of detonation waves, ignition and detonative ignition, and deflagration-to-detonation transition. We perform numerical simulation and mathematical analysis, applied to specific situations of interest in that context.
We also have an interest in thermoacoustics, pulse tube refrigeration and Stirling engines, and in high performance computing and networking.
