Some aspects of two-dimensional compressible turbulent boundary layers
Abstract
Experimental data obtained in nominally two dimensional compressible turbulent boundary layers at supersonic speed are compared with concepts from low speed flows. The validity range of physical models of turbulent flows is considered. Dominating flow parameters and turbulence field changes as compared with low speed flow are discussed. Interpretation of mean flow measurements for zero pressure gradient (adiabatic and isothermal wall); transition and low Reynolds number effects; wall roughness effects; and curvature and pressure gradient effects are treated. The law of the wall and the Crocco temperature velocity relationship are outlined. Interpretation of fluctuating flow measurements, including Reynolds stress effects, is treated.
