ABSTRAKT
The high-speed mixing layers with convective Mach number Mc = 0.4,0.8 and 1.2 are investigated numerically. The present results provide the flow-field structure, the similarity of the mean quantity distributions, the characteristic of velocity fluctuation and the normalized growth rates which all agree with experimental and other numerical results. The scaling analyse shows that the ESS prevails in the inner region of the fully developed mixing layer and compressibility affects little on the scaling exponents. This is consistent with the similar spectra of the velocity in the mixing layers with different Mc.
