The analysis and simulation of the dynamics of a moving boundary between immiscible fluids in a porous medium is presented. One fluid is introduced under prescribed inlet boundary conditions and the motion of the resulting interface boundary is studied. The aforementioned scenario is simulated using a finite element based software, FIDAP. Analytical solutions developed in one dimension illustrate the concepts and serve as a benchmark for numerical solutions. The aim of computer simulation is to develop a model applicable to real situations, yet flexible enough for future adaptations to other problems with little modification.
