Abstract

A finite difference procedure with moving nodal points is presented to analyze a one-dimensional accreting compressible clay cake because of electrical and gravitational forces. The procedure involves solution of a second order, non- linear partial differential equation for cake compression where the cake thickness is modified by employing a no-jump condition at the suspension/clay cake interface. Analytical solutions are obtained for the final cake thickness and steady state porosity distribution. The results of the model are presented graphically and the numerical procedure is verified with the exact solutions. 1 Introduction Leaks in geomembrane liners underneath the waste impoundments cause subsurface contamination.
