Two-dimensional

stationary

compressible boundary layer with zero pressure gradient is numerically simulated with GAO-YONG turbulence model.Employing staggered grid arrangement

SIMPLE/SIMPLER code and a second-order QUICK scheme are used.All the results verify that the GAO-YONG equations

without using empirical coefficients and wall functions

may successfully simulate the compressible turbulent boundary layer (Ma=0.2～2.4).The calculation successfully simulates the flow

including the natural transition process

and predicts the fundamental properties of the boundary layer

such as C_f

the logarithmic law

and the defect law

etc

which are finely close to the experimental data.All the results further verify the adaptability of the turbulence model to real turbulent flow.
