관내 가열 온도에 따른 케로신 연료의 유동 특성

초록

This study experimentally investigated the internal flow and injector-outlet behavior of heated kerosene using a fuel-heating system that simulated a scramjet regenerative-cooling environment. Under single-phase flow conditions, temperature, pressure, and liquid-jet shape remained relatively stable. Under two-phase flow conditions, bubble formation and gas–liquid interface fluctuations increased the temperature and pressure oscillations, while phase change occurred earlier at the lower mass flow rate. Increased interface disturbanceswere also accompanied by irregular near-field liquid-jet behavior.
