The thermophysical and transport properties of the aviation kerosene at various temperatures were obtained by a 10-species surrogate and the NIST SUPERTRAPP software. The grid independence was first studied and numerical results were then compared with experimental data for validation. Effects of mass flow rate, heat flux, pressure, and inlet temperature on the heat transfer performance were investigated. Under flow conditions given in this work, the results show that the heat transfer coefficient increases with mass flow rate, heat flux, or inlet temperature, while an increase in inlet pressure reduces the heat transfer coefficient. The buoyancy force has little effect on heat transfer. PB Begell House LK https://www.dl.begellhouse.com/journals/648192910890cd0e,4860a26f63ba7840,24ecc0284b06d628.html
