溶质运移模型数值解及并行化处理

文章主要是在了解和广泛收集前人研究资料的基础上,将混合拉普拉斯变换有限单元法引入到求解首采区卤水动态二维模型中关于溶质运移的问题中。在求解对流占优的地下水溶质运移问题时,常规数值方法会产生数值扩散和过量现象,而此方法能够有限地消除数值扩散和过量的现象,还具有一步到位、局部求解的优点。最后还将此方法应用到具有空间一阶导数项的对流弥散方程,以检验此方法的数值有效性和求解溶质运移模型的能力。

Numerical Method and Parallel Algorithms for a Solute Transport Model

Solute transport in 2-D dynamic model of brine in first mining area was discussed using hybrid Laplace transform-finite element method.Numerical diffusion and excess may appear when solving convection-dominant solute transport problems with conventional numerical method.By this method,the diffusion and excess can be effectively avoided.As an direct method,it can be used for part solution.Finally,the numerical effectiveness and capacity in solving solute transport model of this method are verified in solving...
