Separation Shock Motion in Fin, Cylinder and Coinpression Ramp-Induced Turbulent Interactions Fluctuating wall-pressure measurements have been made on the centreline upstream of a blunt fin in a Mach 5 turbulent boundary layer. By examining the ensemble-averaged wall-pressure distributions for different...
Stratford's method of computing the development of a turbulent boundary layer in a strong adverse pressure gradient, based on division of the layer into an inner equilibrium layer and an outer layer of almost constant total-head, is simple and is based on current knowledge of the properties of...
The turbulent boundary layer is considered to consist of several regions characterized by their water velocity profile. These regions include the viscous sublayer, the log-law region, and the outer region (Fig. 7.2). Sign in to download full-size image 7.2. Law of the wall plot for a turbu...
The present analysis of turbulent layer separation from a smooth surface, which is based on the method of matched asymptotic expansion for Reynolds number approaching infinity, indicates that this separation, in contrast to the laminar separation case, is not localized in the interaction region. In ...
The boundary layer separates from the location of the wall where the wall flow is fully retarded. In this way the boundary layer separation may take place at the permeable wall and upstream of the wall if injection is at a small angle to the wall and counter the main flow direction. ...
Turbulent boundary layers approaching separation are a common flow situation in many technical applications. Numerous theoretical, experimental and numerical attempts have been made to find the proper scaling for the mean-velocity profile of this type of wall-bounded flow. However, none of these approa...
Turbulent Shock-Wave Boundary Layer Separation and Overexpanded Nozzle FlowThe pressure rise associated with shock wave turbulent boundary layer separation depends strongly on the interaction geometry, Mach Number, and Reynolds Number. Comparison of measurements of the......
