| Abstract: | 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. |
