Abstract

A series of experiments has been carried out in the HEG facility (High Enthalpy Shock Tunnel, Göttingen) to obtain detailed measurements on the HyShotII scramjet configuration under both steady and unsteady combustion conditions. Standard pressure measurements are performed, but a main focus of this campaign is the use of optical and visualization techniques: high-speed visualizations of OH* chemiluminescence together with pulsed-diode laser Schlieren imaging are employed to gain information about the approximate flame location as well as the interaction between the flow features and combustion characteristics. In particular, this allows an unprecedented level of insight into the transient combustioninduced phenomena present in the combustion chamber at high equivalence ratios. Measurements are compared with computational data obtained from the DLR TAU code.
