| Abstract: | A system of quasilinear coupled equations which arise from simulation of contamination of geologic nulear waste in porous media is studied. We'll discuss Galerkin method for the model of compressible flow with molecular diffusion and dispersion. Some new techniques are introcued to error analysis. Only one dimensional case is considered. The optimal error estimate in both L2 and H1 is proved. A contribution of this paper is how the dispersion term can be handled. |
