Abstract: Abstract In the present paper a complete scramjet demonstrator model for experimental testing at Mach 8 is investigated numerically using the scientific code TASCOM3D (Turbulent All Speed Combustion Multigrid Solver) on the HPC vector system NEC SX-9, installed at the High Performance Computing Center Stuttgart (HLRS). First the three-dimensional intake of the model is simulated. Then the results are used as inlet conditions for the simulation of the combustor, where hydrogen is injected by a lobed strut injector located in the middle of the diverging chamber. The test conditions, corresponding to a flight speed of Mach 8 at an altitude of 30 km, and the results of the simulations are discussed in detail, occurring difficulties are highlighted. In order to ensure self-ignition and prevent the flow from blockage, potential design changes are described and investigated in order to proof their functionality. Finally the performance of the reactive and non-reactive simulations on the NEC SX-9 is analyzed.
