Slip boundary effects on compressible turbulent boundary layers under wind-tunnel experimental conditions

Rarefaction effects in compressible turbulent boundary layers is investigated by imposing slip boundary conditions at the wall. The Kolmogorov and viscous length scales are an order of magnitude higher than the molecular mean free path. The influences of the slip boundary conditions on turbulent flow statistics are restricted within the viscous sublayer. The mean wall heat flux, vorticity and velocity divergence fluctuation intensities are obviously affected.
