摘要
以往在用计算流体力学 (CFD)方法计算空气温度时 ,仅考虑空气显热 ,导致计算温度与实际情况相差较大。提出一种考虑潜热的计算房间温度和相对湿度的CFD方法 ,将两种计算结果进行了比较 ,发现前者的计算结果较后者约高 0 .5～ 1℃。
In view of the considerable error in using CFD method to calculate the air temperature due to the latent heat treated as negligible, puts forward a theoretical model taking latent heat into account, which is consisted of enthalpy and vapor concentration equations. By simulating a project with the model, compares the temperature distribution calculation results with and without latent heat in consideration, showing that without considering latent heat will result in a rise in temperature of 0.5-1 ℃.
