Paper Abstract

Theoretical models describing the dynamic behavior of the expansion and contraction of polyelectrolyte gels present numerically challenging problems. This paper describes how a method of weighted residuals approach has been used to solve the two-dimensional governing system of equations by finite element analysis. The modulation of the imbibition/expulsion of solvent by a gel disk is studied as an example.
