Boundary-Layer Separation

, 2017
AbstractChapter 2 discusses the experimental observations of the boundary-layer separation in subsonic and supersonic flows that lead to a formulation of the concept of viscous-inviscid interaction. It then turns to the so-called ‘self-induced separation’ of the boundary layer in supersonic flows.

Unsteady Turbulent Boundary Layers and Separation

AIAA Journal, 1975
The time dependent turbulent boundary-layer equations are integrated numerically with a two-layer eddy viscosity model (Cebeci-Smith formulation), for transient or oscillatory outer flows. Comparisons with previous theoretical results indicate that the present method is at least as good as the others.

DNS OF A TURBULENT BOUNDARY LAYER WITH SEPARATION

Proceeding of Second Symposium on Turbulence and Shear Flow Phenomena, 2001
The present contribution reports on a direct numerical simulation (DNS) of a turbulent boundary layer that undergoes separation due to the presence of a pressure gradient at a moderate Reynolds number. The variation of the free-stream velocity has been chosen according to an experiment of Kalter and Fernholz (The influence of free-stream turbulence on ...

Note on Unsteady Boundary-Layer Separation

AIAA Journal, 1974
turbulent. It was assumed that in this case, the aft microphone gave a more realistic representation of the acoustic environment. In addition, it was assumed that the disturbance function Z was comprised solelv of acoustic disturbances. A plot of transition data obtained in the AEDC 16T as a function of acoustic level is shown in Fig. 3.

Prediction of Turbulent Separated Boundary Layers

AIAA Journal, 1973
Theme A integral boundary-layer method is extended to calculation of separated turbulent boundary layers by treating the pressure as a dependent variable and prescribing the wall shear variation. The boundary-layer method and a suitable potential flow method are used in an iterative procedure to produce a method for predicting the characteristics of ...

Boundary layer separation in a rotating container

Physics of Fluids, 1996
The flow field induced in a cylindrical container by the rotation of the container and/or the end wall(s) about the axis of symmetry is highly vortical. If the container and the end walls are rotated at different angular velocities, a meridional flow develops due to the tilting and stretching of the axial vorticity created by the rotation of the ...

Boundary-Layer Separation in Unsteady Flow

SIAM Journal on Applied Mathematics, 1975
Extension of the familiar concept of boundary-layer separation to flow along moving walls and unsteady flows is a subject that attracted some interest in the 1950’s and has been investigated further in the past few years. The well-known criterion of vanishing wall-shear does not apply in such flows, and therefore the definition of the phenomenon ...
