摘要
本文提出了数值求解一维对流-扩散方程的一种高精度优化差分格式,计算了三个典型问题并和前人工作进行了比较,获得了更加令人满意的结果。
In this paper, an optimal difference scheme with high accuracy is suggested for solving one-dimensional convection-diffusion equation numerically. The scheme is used to solve three typical test problems, their numerical solutions are separately compared with those obtained in the previous work, and analytic value. The present scheme gives better results.
