摘要
本文用边界元法解决非稳定系统中水质预测的计算问题,建立了三维水质预测问题的边界元法计算模型,为简化计算手续、提高计算精度,讨论了Laplace变换边界元法,推广了Laplace变换边界元法中的Schapery方法。
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.
