本文对二维超声速混合层进行了数值模拟，采用两种不同的激励方式，即在入口处引入T-S波和在低速侧加强来流速度，使其具有周期性的流向波动。结果表明，当对流马赫数Mc小于1时，两种方法都有效，但后者比前者更有效。系统地计算了不同参数对混合的影响。
Numerical simulations have been performed for a 2D supersonic mixing layer with two different types of excitation, namely the introduction of a T-S wave at the inlet and the enforcement of the inflow speed on the low speed side to have periodic stream-wise undulations. The results showed that both ways were effective when the convective Mach numberMc was less than 1, but the latter was more effective than the former. Systematic computations have also been done to analyze the effect of different parameters on mixing.
