Abstract

An axisymmetric, contoured nozzle is designed for the High Enthalpy Wind Tunnel Goettingen (HEG). In the conical part of the expansion the flow is calculated using a quasi one-dimensional approximation, taking into account finite rate chemical kinetics. Assuming a source flow and species freezing at the end of the conical section, the contoured part of the nozzle contour is subsequently determined using the method of characteristics for a perfect gas. The physical nozzle contour is f inally obtained by adding the boundary layer displacement thickness, calculated by using an empirical correlation, to the inviscid contour. In addition to the discussion of the performance at off-design conditions, different chemical models and rate constants are used in the quasi one-dimensional calculations in order to investigate the influence on the flow properties.
