【Abstract】

<正>Turbulence in the compressible channel flow is studied by direct numerical simulation at Re_Γ= 430 with Ma = 1.5,3.0,6.0 and modelled by multi-layer structure theory.As an extension of the mixing length for incompressible flow,an efficient Reynolds stress is defined and a closure new length order function LM~+ in stream-
