Similitude Properties of High Speed Laminar and Turbulent Boundary Layer Incipient Separation.
Abstract
Following a brief review of existing experimental knowledge about the important parameters in influencing high speed boundary layer separation, a systematic analysis is made of the various similitude rules pertaining to incipient separation including viscous-inviscid interaction for both laminar and turbulent flows. For supersonic and hypersonic turbulent flows a new scaling rule is derived which, unlike existing ones, agrees with the general trend of experimental data at high Reynolds numbers. The corresponding lateral pressure gradient effects are also examined and shown to be significant for such turbulent flows throughout the entire speed range.
