摘要
基于待定系数法,采用分步离散解法对一维对流扩散方程进行了求解。数值试验结果表明,本文建立的格式可以同时使得格式的数值振动和数值扩散达到最小,能较好地模拟对流扩散波的传播过程。
One-dimensional convection-diffusion equation is solved by multistage discrete method of Indefinite Coefficient Algorithm. The results of numeric solution show that the scheme established in this paper can reduce the numeric fluctuation and dispersion to the least, and simulate the process of convection-diffusion well.
