Experimental investigations on heat transfer of RP-3 kerosene at supercritical pressures are conducted in this paper. It is found that there are three regimes, namely common heat transfer, enhanced heat transfer and deteriorated heat transfer. Variations of thermal properties are responsible for common heat transfer. Turbulence is the main reason for enhanced heat transfer. Cracking reactions are attributed to deteriorated heat transfer. Parametric studies show that heat flux has little effects on heat transfer of RP-3 at supercritical pressures while mass flow rate plays a positive role. Influence of pressure is complicated, related to thermal property variations. A new correlation for heat transfer of RP-3 flowing in miniature tube at supercritical pressure is proposed.
