微沟槽表面对池沸腾传热影响的仿真研究
Simulation Study on Effect of Micro-groove Surface on Heat Transfer of Pool Boiling
摘要
Abstract
Based on the theory of fluid mechanics,the numerical model of gas-liquid transfer heat of micro-groove structure was established by using Fluent software,and the influence law of nine micro-groove structure surfaces on pool boiling heat transfer was analyzed.The heat transfer surface tempera-ture,surface heat transfer coefficient were compared and analyzed.The results show that the surface of micro-groove structure has better boiling heat transfer effect than that of smooth surface.The surface temperature of heat transfer decreases monotonically with the increase of groove depth and the decrease of groove width.With the same groove width,the heat transfer coefficient increases with the increase of groove depth.When the depth of the groove is the same,the width of the groove has little effect on the heat transfer coefficient.When the groove width is 0.1mm,the groove depth is 0.2mm and the rib width is 0.1mm,the surface temperature of micro-groove is the lowest and the heat transfer coefficient is the highest,and the temperature decreases 3.63%and the heat transfer coefficient increases 80.43%com-pared with the smooth surface.关键词
