EXPERIMENTAL STUDY ON TRANSCRITICAL SPRAY OF LIQUID AVIATION KEROSENE
ABSTRACT
High-speed photography was used to study the transcritical spray of liquid aviation kerosene into supercritical environments. The transcritical spray patterns under different conditions were investigated, and the reason spray patterns and breakup length vary was analyzed. It was discovered that ambient temperature and Reynolds number dominate the transcritical injection patterns, and the ambient temperature influences the injection patterns most under transcritical conditions while the Reynolds number is the most important parameter when ambient pressure is subcritical. It was also shown that the "continuous mist" form emerges when the ambient pressure is larger than 2 MPa and the Reynolds number is larger than 5400, and this pattern is unique to transcritical injection. An empirical formula that can predict the breakup length of transcritical injection well was obtained via modifying the previous formula and fitting the experimental data.
