Scotland,The following cases of diffusion-evaporation for a solid sphere with radial transfer and constant diffusivity, are of interest. The initial concentration within the sphere is considered uniform:

The Law of the Excluded Middle: A DigressionTesting of rubber materials involves exposure to various types of environmental factors: temperature, which plays a part in all environment tests, moisture, steam, liquids and gases.

The Law of the Excluded Middle: A DigressionThe process of drying of plasticised PVC appears to be strange at first, but it can be explained by the formation of steep gradients of concentration which play a important role when the diffusivity is concentration dependent.

Principles and General Equations,The general problem of the drying of solids can be complex as three types of transport exist for liquid and vapour (Fig. 1.1):

Thin Plane Sheet,Various cases of one-dimensional diffusion in a solid bounded by two parallel planes, with evaporation on the surfaces, are considered. The plane sheet is so thin that all the liquid evaporates through the plane surfaces and a negligible amount through the edges, and the diffusivity . is constant.
