Modelling and Quantification of Gas Flux through an Artificial Epidermis

A general model of transport of gases in an artificial epidermal layer (membrane) was established. The model was developed based on Dusty Gas Model (DGM), solution diffusion and surface diffusion. As a result, solutions of the model for different transport conditions were derived. In this investigation, parameters of oxygen and carbon dioxide gases through an artificial “epidermal” membrane of varying porosity were used to calculate semi-empirical solutions of the general model. In other words, the solutions of the general model were analytically obtained for different transport conditions, using experimentally obtained parameters of oxygen and carbon dioxide gases through the artificial “epidermal” membrane of varying porosity. The obtained solutions of the general model were for the oxygen and carbon dioxide gases through the artificial “epidermal” membrane of the varying porosity.
