Other AbstractThe flow-field in the supersonic combustor has the characteristics of high speed, high temperature, high background radiation, and so on. Thus, the visualization of flow-field in a supersonic combustor is difficult. According to above characteristics, a pulsed schlieren system was developed, and a short exposure time was chosen to freeze the flow-field. On the other hand, compared to the electric flash energy, the background radiation could be ignorable during the exposure time. Thereby, the effect of background radiation is eliminated effectively. The pulsed schlieren system is used to study the flow-field structures during the combustion process of supercritical kerosene in a Mach number 3.0 supersonic flow. Schlieren images clearly show flow-field structures and their evolutionary process.
