摘要：

A new model is proposed for entrainment in supersonic turbulence. The central assumption is that only those eddies whose rotational Mach number is unity directly engulf fluid. With the additional assumption that a Kolmogorov spectrum of eddy scales exists for all subsonic eddies, the theoretical effect of the sonic eddy on entrainment and structure is compared to observation in shear layers and wakes.
