Drying of a Polymer Sphere with Shrinkage
During the process of absorption of a liquid by a polymer, swelling very often takes place, especially when the amount of liquid absorbed is large. Shrinkage of this polymer is thus observed during the process of desorption. The process is controlled by transient diffusion of the liquid within the polymer and evaporation from the surface. To obtain analytical solutions the mathematical treatment neglects the change in the dimensions of the polymer. Very often, numerical models with finite differences are built by considering a framework of reference with constant dimensions.
