摘要: 本文提供了一种三维非定常流的有限差分方法。是一种拉格朗日方法。本文构造了一个二十四面体。将动量守恒方程在这个二十四面体上积分,建立的差分方程,形式简单,容易计算。

Abstract: In this paper a finite d if ference code for three dimensional unsteady flow has been provided.It is a Lagrangean method.we have constracted a ic-osotetrahedron. we have integrated the equation of momentum over the icosot-etrahedron and estaklished the difference equation.It is simple and easy to calculate
