Applications of Non-Linear Diffusion Equations to the Kinetics of Water Vapour Adsorption by Polymeric Fibres

Applications of Non-Linear Diffusion Equations to the Kinetics of Water Vapour Adsorption by Polymeric Fibres

In order to describe the kinetics of water vapour adsorption by polymeric fibres, a numeric experiment has been carried out using the framework of a non-linear diffusion model which takes into account the exponential dependence of the diffusion coefficient on the sorbate concentration in the sorbent...
