摘要
基于二阶线性偏微分方程的差分数值解法,推算出抛物线型和椭圆型两类偏微分方程的差分计算公式、计算程序表及所采用的Excel计算格式,并用流体力学上的两个实例加以验证。结果表明,利用Excel软件计算具有赋值准确、计算快速准确等优点。
The numerical method is used to solve the second order linear partial differential equation(PDE), and the use of the Microsoft excel in solving the equation is introduced. Two hydraulic problems of the parabolic type and elliptic type equation are chosen and calculation in this paper. In each problem , the differential and iterative form of calculation, the program table ,and excel formulae are deduced. The calculated results are satisfactory.
