| 英文摘要 | A series of Mach-number- (M) invariant scalings is derived for compressible turbulent boundary layers(CTBLs), leading to a viscosity weighted transformation for the mean-velocity profile that is superior to van Driest transformation. The theory is validated by direct numerical simulation of spatially developing CTBLs with M up to 6. A boundary layer edge is introduced to compare different M flows and is shown to better present the M-invariant multilayer structure of CTBLs. The new scalings derived from the kinetic energy balance substantiate Morkovin’s hypothesis and promise accurate prediction of the mean profiles of CTBLs. |
