| 摘 要： | 有限分析法是一种有效的用于流体计算的数值方法。但是用传统方法来计算有限分析系数相当繁琐、耗时,在有些情况下不够准确甚至完全失真。本文给出一个近似公式,利用它可很方便地求出有限分析系数,误差在0.003以内。

| Abstract: | The Finite Analytic Method (FA)is an efficient numerical method to solve the fluid flow problems . However, the calculation of Finite Analytic Coefficients by the conventional method is bored and time consuming . Moreover,in some extreme cases the resulted coefficients may become totally erroneous. This paper presents an approximate formula to determine FA coefficients . which is convenient to use. The error caused by the approximaion is less then 0.003. |
