摘要
以模型方程为例,采用MUSCL插值的S-W通量分裂格式,分别结合二步、四步龙格-库塔时间推进格式建立数值求解方法。用Von Neumann傅里叶级数分析方法,通过对不同格式的放大因子及色散因子的计算,分析了时域有限体积法(FVTD)格式的稳定性。
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.
