Theoretical, Numerical and Experimental Treatment of Combustion, Research Plan and Reflections on the PSAAP Approach

Abstract: Theoretical approaches for CFD of turbulent combustion will be summarized as well as fundamental combustion experiments performed at Eindhoven University of Technology. First, the Flamelet Generated Manifolds (FGM) technique will be introduced, with its relation to subfilter scale LES modelling w.r.t flame turbulence interactions. Next, the mass-based stretch theory and application will be treated, concluding with the heat flux method (HFM) for determining adiabatic gaseous burning velocity experimentally. Canonical cases will be gone into, especially for carbon free fuels. Additionally, Professor Bastiaans will present his plans for researching CFD of combustion of ammonia/hydrogen mixtures while visiting the Center for Turbulence Research. The lecture will conclude with initial insights gained in the PSAAP project, with a personal vision on preferred sequential steps to be executed.

Bio: Rob Bastiaans is an Associate Professor in the Department of Mechanical Engineering, Eindhoven University of Technology (TU/e), group Power & Flow. In this capacity, he is also Chairman of the Dutch Section of the Combustion Institute and Chairman of the Dutch section of IFRF (International Flame Research Foundation). Rob’s areas of expertise include fluid mechanics modeling, experiments and simulation, including turbulence and combustion specifically. Current research comprises the reduction of computational resources, with respect to efficiency as well as accuracy for both kinetics (FGM) and aerodynamics (LES), and their combination. Everything for carbon free fuels, in particular ammonia and hydrogen, looking at preferential diffusion aspects and NO_x emissions.
