| Abstract: | The BEM is a numerical method developed in the past ten years. It has the virtue of reducing the domain of calculation and has been applied on electromagnetism, solid mechanics and mechanics.However,the BEM has not been widely used in the hydrodynamic dispersion-diffusion equation.In this paper, the BEM has been used to solve numerical calculation problems of the hydrodynamic dispersion equation, and the Schapery Method in Laplace transform BEM has been extended. |
