Comparative Study of Two Hygrothermal Analysis Methods in Hygroscopic Region

扫码查看
This paper showed difference in calculation results between two methods of hygrothermal analysis in hygroscopic region. Two methods differs in the expression of moisture flux. In one method, moisture conductivity varied with relative humidity is used without liquid term. In the other method, a constant vapor permeability is used with liquid term. The calculation results are different for an example of relative humidity difference given at both sides of a wall.
