Experimental investigation of convection heat transfer of Fe3O4-kerosene at supercritical pressures

摘要：

　　An experiment on the heat transfer characteristics of Fe3O4-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 as mass flow rate,heat flux,pressure and particle content.Results show that increasing the flow rate or the working pressure could enhance the heat transfer performances,yet the heat transfer coefficient decreases with heat flux increases.Besides,the addition of solid particles deteriorates the heat transfer performances through the modification of inner wall surfaces.As the particle content increases,the heat transfer performance becomes worse.Based on the experimental data,a correlation for predicting heat transfer of Fe3O4-kerosene at supercritical pressure is established and shows good agreement with the experimental data.
