基于Yanenko计算高维问题的时间分裂(Time Split)思想,并结合Eulerian—Lagrangian法求解对流—弥散高程的有效性,本文提出了一种计算地下水中溶质运移的数值法。该方法将多维问题分解成几个一维问题,有效地减少了计算工作量,并消除“数值波动”现象,实例计算结果表明,本方法具有较高的精度。 Based on Yanenko’s idea of ​​time-splitting high-dimensional problems and the Eulerian-Lagrangian method to solve the convective-diffusive elevation, a numerical method for calculating solute transport in groundwater is proposed in this paper. The method decomposes the multi-dimensional problem into several one-dimensional problems, effectively reduces the computational workload and eliminates the phenomenon of “numerical fluctuations.” The calculation results of the examples show that the method has higher accuracy.
