Analysis of Gas Relative Diffusion Characteristics for Porous Material with Liquid Water

摘要：

In this study, a method for calculating relative diffusivity of gas in a porous material based on pore size distribution is proposed. The calculation results show that it is not only the saturation that has an impact, but that the pore size distribution of the gas diffusion layer should also be considered when calculating the relative diffusivity of porous material with liquid water. In addition, the calculation formula proposed in this paper explains the results of experiments in the relevant literature, that is, the relative diffusivity showed almost the same value for porous materials having different pore size distributions.
