Abstract: Abstract A numerical and experimental analysis of a Scramjet intake flow has been initiated at RWTH Aachen University as part of the Research Training Group GRK 1095: “Aerothermodynamic Design of a Scramjet Engine for a Future Space Transportation System”. This report presents an overview of the ongoing work on numerical simulations using Reynolds averaged Navier-Stokes solvers. Two different geometry concepts in 2D and 3D are investigated using several turbulence models to point out the influence of the geometry on the flow behaviour. One with a double ramp/convex curve configuration, the other with a double ramp/convex corner configuration. The data obtained will be compared with results from experiments which will be started in autumn 2006. It has to be said that not all results presented here were achieved using the NEC computing cluster. For comparison several calculations were conducted on the IBM Jump system of the Jülich Research Centre and at the SUN cluster of RWTH Aachen University. At the end of this report the computational performance will be compared.
