NUMERICAL SIMULATION OF A HYDROGEN FUELLED SCRAMJET COMBUSTOR USING LARGE EDDY SIMULATION
Large eddy simulations for a hydrogen-fuelled scramjet combustor have been performed using the dynamic Smagorinsky model with Lagrangian averaging technique. Both non-reacting and reacting cases have been investigated. The physical configuration corresponds to the scramjet combustor experimentally investigated at the Institute for Chemical Propulsion of the German Aerospace Center (DLR). Favre-averaged transport equations for mass, momentum, energy and species concentrations are solved using finite volume discretization scheme in OpenFoam. Single-step global reaction is used for the partially stirred reactor (PaSR) combustion model. Numerical results for time averaged pressure, temperature and axial velocity are compared with experimental data at different cross-sections of the combustor.
