Abstract

In the present experimental study, injection of subcritical and supercritical kerosene into a high-temperature and highpressure subsonic crossflow was investigated. Visualization and characterization of the jet structures were performed using schlieren imaging, from which the jet penetration trajectory was determined. For the conditions tested, a correlation of jet penetration trajectory was developed, with momentum ratio as the primary parameter. An analysis based on one-dimensional isentropic flow was also conducted to calculate the flow parameter variations in the nozzle and along the jet trajectory. Using a three-component kerosene surrogate, the phase transition processes for supercritical and subcritical kerosene jets were illustrated in the thermodynamic phase diagram. Experimental and analytical results demonstrated that the behavior and penetration of supercritical kerosene injection into high temperature and high pressure crossflow were closer to those of the case with gas jet injecting into a gas crossflow than the case with liquid kerosene injection.
