摘要
将Steger Warming矢通分裂方法和NND格式相结合构成一种基于Steger Warming矢通分裂且能自动捕捉到激波的差分算法。通过对激波管和对可燃气体DDT过程的数值分析证明该算法解决了Steger Warming矢通分裂方法在零特征点附近存在数值解震荡的问题 。
The NND scheme based on Steger-Warming flux vector splitting was presented. The flow field of shock wave tube and gas DDT process was calculated by the finite difference method presented in this paper. It is showed that the numerical oscillation brought by Steger-Warming flux vector splitting was restrained. The finite difference method has fine precision and efficiency.
