Numerical Investigation of Double-Cone and Cylinder Experiments in High Enthalpy Flows using the DLR TAU code

Abstract

In the framework of validation and further development of the DLR TAU code for hypersonic applications several laminar calculations were conducted participating in a RTO working group. The enthalpy in the generic test cases ranges from 5 to 22 MJ/kg addressing thermo-chemical relaxation processes in air and pure nitrogen. Strong bow shocks as well as boundary layer separation, shock-shock and shock-boundary layer interactions are present in the flow fields. The applied numerical models are discussed. The comparison with the experimental data shows the current capability of the DLR TAU code to predict the aero-thermodynamic loads and how model improvements can be supported by these experiments.
