Effect of External Induced Convection on Heat Transfer at Water Boiling

In this paper, we experimentally and theoretically study the effect of external induced convection on heat transfer from horizontal heaters under conditions of pool boiling of saturated water at atmospheric pressure. The induced convection is shown to significantly affect the heat transfer in the natural convection mode and hardly affects the heat transfer in the nucleate boiling mode. The proposed model for calculating the heat transfer coefficient at the heat transfer intensification due to external induced convection is in good agreement with the experimental data. The results of the study can be used in the design of heat exchange equipment for the needs of the nuclear power industry.
