摘　　要：建立多孔介质平板结霜过程的数学模型,编制相应的仿真程序.获得了质量流量,霜层厚度,霜层表面温度,霜层密度,偏重系数的相互影响关系.计算结果和实验测试的结果吻合,研究对确定多孔介质平板结霜的霜层生长速率计算有较大参考意义.The mathematical models and simulation programs of a flat plate of porous structure have been set up. The different relations such as mass transfer at the frost layer, frost thickness, surface temperature at the frost layer,frost density and weighting factors have been obtained. The computing results are in good agreement with those from experiment. The conclusions in this paper are of great significance for the design of the frost growth rate.
