| Abstract: | The numerical value dividing method was established through using MUSCL schemes, Steger-Warming flux vector splitting,and two and four steps Runge-Kutta integration based on the model equation in this paper.The format stability of finite-volume time domain method was analyzed by computation of magnified gene and dispersive gene for different formats were computed using Von Neumann Fourier series analysis method. |
