CFD simulation was applied to describe the combustion processes in a high-speed hydrogen engine, based on the flame area evolution (FAE) combustion model. The simulated courses of in-cylinder pressure and heat-release rates significantly depend on the estimation of temperature effect on burning velocity. They can be well reproduced in a range of conditions including high-speed operations as long as the turbulent burning velocity is appropriately estimated as a function of pressure, temperature, mixture concentration and turbulence characteristics.
