摘要: 本工作改进了Denton的有限体积的时间推进法,将这种对时间一阶精度对空间二阶精度的方法改进为对时间二阶精度对空间二阶精度的计算方法,并应用于S型进气道的内流及具有进口外流的进气道流场的数值模拟,进行了实例计算,取得了合理的计算结果。

Abstract: In this paper, Denton's time Marching Method infinite-volume is modified from the 1st order accuracy in time and the 2nd order accuracy in space to the 2nd order accuracy in time and in space. It is applied to numerical simulation of s-Inlet flows with and without external flow. Satisfactory results are achieved.

Key words: inlet, numerical calculation, numerical simulation
