A research on the heat transfer performance of kerosene flowing in a vertical upward tube at supercritical pressure is presented. In the experiments, insights are offered on the effects of the factors such asmass flux, heat flux, and pressure. It is found that increasing mass flux reduces the wall temperature and separates the experimental section into three different parts, while increasing working pressure deteriorates heat transfer. The extended corresponding-state principle can be used for evaluating density and transport properties of kerosene, including its viscosity and thermal conductivity, at different temperatures and pressures under supercritical conditions. For getting the heat capacity, a Soave-Redlich-Kwong (SRK) equation of state is used. The correlation for predicting heat transfer of kerosene at supercritical pressure is established and shows good agreement with the experimental data.
