| Abstract: | An analytical expression of shear stress integral for moment-of-momentum equation is derived by two-layer eddy viscosity turbulence model and the power law of the velocity profile. Thus the calculation of the compressible turbulent boundary layers is significantly simplified. The analytical expression is in good agreement with experimental data than other theoretical results |
