摘要
考虑修正NLG(一种变模形式非线性Galerkin)方法求解二维Navier-Stokes方程的 全离散形式,通过一个例子的数值实现,按几种不同形式作了计算,数值算例表明了在不损失精 度的情况下,修正NLG方法于CPU耗时方面有明显的节省。
We consider in this paper the full discretization of modefied NLG method (a kind of nonlinear Galerkin method with variable modes) for solving two-dimensional Navier-Stokes equaitons. We make the computing inseveral models to the numerical implementation of an example. This numerical example shows us that the modefied NLG method has a significant save in CPU time without the loss of computational precision.
