Abstract

The mean velocity and pressure fields in a turbulent boundary layer on a flat plate at M_∞ = 2.6 are investigated for ratios of mass flow per unit area injected at the wall to that at the edge of the boundary layer Λ_e) between 0 and 0.03. Two dimensionality is demonstrated, and a similar flow established with linear growth of momentum and displacement thicknesses. A Howarth-Dorodnitsyn transformation for the normal coordinate is found to bring the data into good agreement with incompressible results for the same value of Λ_e. At the highest injection rate, the velocity profiles agree well with turbulent mixing-layer results. However, unlike mixing layers, the maximum rate of mass entrainment is the same as for the incompressible case. Finally,the induced side forces are found to be comparable to those obtained by equivalent inje ction thr ough a slot.
