Abstract
In order to investigate the developing characteristics of a high temperature supersonic impulse jet under an atmospheric ambient condition, we generate jets induced by an incident shock wave at Mach number 2.89, emerging from the open end of a high enthalpy blast wave simulator (HEBS). Developing high temperature supersonic impulse jets were visualized by the direction-indicating color schlieren method and analyzed by numerical calculations. A comparison of the experimental results with literature shows that the unsteady boundary area generated by the HEBS, starts to grow in half the time that the unsteady boundary area needs after the incident shock wave emerges in the literature.
