Active Control of Separating Boundary Layer
PAMM, 2010AbstractFlow control refers to the ability to alter flows with the aim of achieving a desired effect: examples include drag reduction, noise attenuation, improved mixing or increased combustion efficiency among many other industrial applications.

A Turbulent Boundary Layer Approaching Separation
1982Measurements and calculations of the pressure and velocity characteristics of a two-dimensional boundary layer approaching separation are presented and compared. The velocity measurements were obtained with a combination of impact probes, stationary and flying hot wires and quantify, for example, the rapid growth of the boundary layer as separation is ...

Boundary layer separation of hydromagnetic flows
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2012AbstractThe influence of the magnetic field on the boundary layer separation of a two‐dimensional incompressible flow of a conducting fluid subject to a non‐slip boundary condition is studied. It is found that the key factor differentiating this phenomenon from the hydrodynamic case is the angular velocity of the magnetic field at the boundary wall ...

Transition in a Separated Laminar Boundary Layer
Journal of the Aerospace Sciences, 1960PROGRESS in understanding the mechanism of transition from laminar to turbulent flow in a boundary layer has been largely confined to flow along a flat plate. The present investigation is concerned with transition in a separated laminar boundary layer. A hot wire investigation of flow near the short leading-edge bubble on a RAE-103 airfoil section led ...

Two-dimensional separating turbulent boundary layers
AIAA Journal, 1986It is shown that mean flow similarity based on a velocity scale related to the maximum shear stress (SchofieldPerry similarity) can accurately describe detached two-dimensional turbulent boundary layers provided the origin of the similarity is relocated on the zero velocity streamline in the detached flow.

Steady and Unsteady Boundary-Layer Separation
Annual Review of Fluid Mechanics, 1986The inspiring review oflaminar separation by Brown & Stewartson (1969) begins thus: "The phenomenon of separation is one of the most interesting features of the motion of an incompressible fluid past a bluff body at high Reynolds number. Here the main stream, which has hitherto been in close contact with the body, suddenly, and for no obvious reason ...

Analysis of separated boundary-layer flows
2008A method for predicting the strong interaction between the viscous and inviscid flows which occurs in flow separation is reviewed. An inverse boundary-layer procedure approximately accounts for normal pressure gradients that may be important in strongly interacting flows.

A three-dimensional boundary-layer separation
Journal of Fluid Mechanics, 1980A nonlinear three-dimensional boundary-layer problem governing the flow upstream of a particular disturbance (e.g. a shallow obstacle) at the wall is considered. The upstream response, a free interaction, takes place under zero displacement of the boundary layer, and the solution is found numerically using Fourier series truncation and varying the ...
