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.
