To better understand the combustion characteristics of a vitiated air heater (VAH) in a direct-connect supersonic combustor, we conducted a Large Eddy Simulation (LES) using the ‘reactingFoam’ solver from OpenFOAM. The VAH comprised a GH2/GO2 single coaxial shear injector for heat addition, surrounded by 24 air injectors for air supply and film cooling. The combustor wall could be thermally insulated by introducing coolant injection and additionally, the turbulent motion could be promoted in the combustion zone. The combustion process, completed within the initial one-third length of the combustor, results in a uniform total temperature distribution that aligns with the intended adiabatic flame temperature.
