Abstract
The mean velocity and pressure fields in a turbulent boundary layer on a Hat plate at M∞ = 2.6 are investigated for ratios of mass-How 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 How approached 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 transformed velocity profiles agree well with incompressible turbulent mixing layer results. Finally, the induced side forces are found to be comparable to those obtained by equivalent injection through a slot.
