摘要：
Characteristics of turbulent flow and heat transfer of compressed liquid kerosene were studied experimentally with sudden changes of the inlet mass flow rate. Flow and heat transfer experiments were conducted at a fuel temperature range of 300-650K, a Reynolds number range of 3000-60000 and a supercritical pressure of 3MPa. The fuel temperature, pressure and mass flow rate, and tube outside wall temperature were measured. Fuel skin friction coefficient and Nusselt number were calculated through unsteady control volume analysis based on momentum and energy conservations. The present results show that the time change of mass flow rate has very little effect on the skin friction coefficient and Nusselt number for compressed liquid kerosene tube flow when the temperature of kerosene doesn't exceed critical value 650K. © 2018, Editorial Department of Journal of Aerospace Power.
