摘要
通过对颗粒多孔层几何结构、沸腾两相流及传热的理论分析，提出了微型通道薄膜环状蒸发物理模型和沸腾传热机理，建立了颗粒多孔表面强化沸腾传热动力学模型。该动力学模型与实验数据吻合良好，可用于工程设计。
Based on the theoretical analysis of the geometric structure, two-phase flow and heat transfer of boiling of powder porous surfaces,a physical model about microchannel annular thin film evaporation and boiling heat transfer mechanism were proposed, and a dynamic model about enhanced boiling heat,transfer in powder porous surface was also presented. The dynamic model is proved to be in good agreement with the experimental data. It can be used for engineering design.
