Verification to stability of difference scheme for convection equation
摘要
Abstract
The paper decided the stability of different difference schemes of the one dimension convection equation using Fourier stability analysis. The fundamental idea of Fourier stability analysis is to extend periodically the error of solution for the linear differential equation and express it using Fourier series, then check the enlargement and decay of every component of the Fourier series. According to Fourier series for each component change over time, we judged the stability of difference schemes by the magnification factor. Using the method, the paper decided the stability of different difference schemes for the given equation.关键词
