| 摘 要： | 针对解溶质运移模型会出现数值误差的问题,结合特征线法求解对流问题和有限分析法能求单元解析解的优点,推导得到了求解对流扩散方程的特征有限分析格式。算例表明,该格式有较高的计算精度,是对有限分析格式的拓展。

| Abstract: | Aiming at the numerical error of solution for solute transport model,combining with the merit of characteristic line method of solution for convection problem and finite analytic method of solution for element analytic solution,characteristic finite analytical model is derived which solute for convectiondiffusion equation.The numerical examples show that the model is of higher calculation precision,and is the continuation of finite analytical model. |
