Abstract: Based on the local discontinuous Galerkin methods for time-dependent convection-diffusion systems newly developed by Corkburn and Shu, according to the form of the generalized convection-diffusion equations which model the radial porous flow with dispersion and adsorption, a local discontinuous Galerkin method for radial porous flow with dispersion and adsorption was developed, a high order accurary new scheme for radial porous flow is obtained. The presented method was applied to the numerical tests of two cases of radial porous, i. e., the convection-dispersion flow and the convection-dispersion-adsorption flow, the corresponding parts of the numerical results are in good agreement with the published solutions, so the presented method is reliable. Reckoning of the computational cost also shows that the method is practicable.
