An experiment on the heat transfer characteristics of Fe3O4-kerosene flowing in a vertical upward tube at supercritical pressure was conducted. In the experiments
the effects of such factors as mass flux
heat flux
pressure and particle content were investigated. There were different heat transfer mechanisms along the tube. Increasing flow rate or working pressure could enhance heat transfer performance
but higher heat flux led to poorer heat transfer performance. Besides
addition of solid particles deteriorated heat transfer performance through modification of inner wall surface. Based on the experimental data
a correlation for predicting heat transfer of Fe3O4-kerosene at supercritical pressure was established and showed good agreement with experimental data.
