Basic aerodynamic configurations are well suited to study fundamental aspects of high enthalpy flows. A test campaign of the flow around a cylinder has been performed in the High Enthalpy Shock Tunnel Göttingen, HEG. Measurements of the density distribution in the shock layer as well as surface pressure and heat flux were taken. The flow in the shock layer is subjected to various relaxation phenomena and therefore the presented measurements provide a useful basis for the validation of physico-chemical models used in CFD codes. This paper presents results of the test campaign and comparisons of measurements to the numerical computations. The sensitivity of the CFD results to different parameters of physico-chemical models is also discussed.
