Latest Calibration Results of the HEG Contoured Nozzle

Kurzfassung

Results obtained in calibrating the nozzle exit flow of the HEG facility at four conditions are discussed. A rake was used to measure Pitot pressure profiles at two axial locations in the test section. For a finer resolution of the boundary layer, a smaller rake was positioned at the nozzle exit. The experimental data are compared with results obtained from nozzle flow calculations using an upwind TVD Thin-Layer Navier-Stokes code, which takes into account thermal and chemical nonequilibrium.
