Experimentelle Untersuchungen zur Düsen- und Heckströmung eines Scramjets

In the framework of the present thesis two different Single Expansion Ramp Nozzles (SERN) were experimentally investigated. For these experimental investigations existing measurement techniques (PSI, Pitot, Schlieren photograph) and additional measurement methods (Pressure Sensitive Paint, IR-Thermography) were applied in order to obtain information about the pressure and temperature distribution on the surface of the expansion ramp. The present thesis researched the influence of flow parameters such as of the nozzle total temperature, of the heat capacity ratio, of the nozzle pressure ratio and of the free-stream Reynolds number on the interactions between the nozzle and the external flow, on the pressure distribution and on the gross thrust of scramjet nozzles. The influence of these parameters on the flow topology along the expansion ramp could be analyzed by means of the IR-thermography and the PSP method, the influence on the interactions between the nozzle and the external flow in the wake of the nozzle by means of Pitot pressure measurements.
