摘要
介绍了2种基于迎风格式和Runge-Kutta法而改进的微分方程差分格式,这2种格式较传统方法在稳定性方面有明显提高,此应用于求解对流方程,改进的迎风格式适用于线性对流问题,改进的R-K法可顺利计算非线性问题.
Based on upwind scheme and Runge-Kutta method, two new difference schemes improved for solving convection equation are introduced. Compared with those traditional methods, the two schemes have been obviously enhanced in stability. They are used to solve convection equation experiment, improve upwind scheme firing linear convection equation, and the latter can solve non-linear convection equation smoothly.
