几种典型的显示差分格式及对N—S方程的两种
首发时间:2009-06-24
摘要:有限差分法是数值求解微分方程的一种重要工具,按离散方式不同可分为显式差分和隐式差分两种形式。本文主要介绍了显式差分格式的几种典型形式,并用两种方法对流体力学中常用的N—S方程进行离散公式的推导,希望结果有一定的参考应用价值。

Several Typical Explicit FDM Methods and Two Discretization Methods to N—S Equations
Abstract:FDM (Finite Difference Method) is an important method to solute the differential equations. It can be divided into explicit and implicit methods in different ways. This paper mainly introduces several typical forms of the explicit method, and also used two methods to discrete the N-S equations .It is hoped that the results will be valuable.
Keywords: explicit FDM method N—S equations time forward difference space central difference
