In fluid dynamics, flow separation or boundary layer separation is the detachment of a boundary layer from a surface into a wake. A boundary layer exists whenever there is relative movement between a fluid and a solid surface with viscous forces present in the layer of fluid close to the surface. The flow can be … See more The flow reversal is primarily caused by adverse pressure gradient imposed on the boundary layer by the outer potential flow. The streamwise momentum equation inside the boundary layer is approximately stated as See more The tendency of a boundary layer to separate primarily depends on the distribution of the adverse or negative edge velocity gradient See more When the boundary layer separates, its remnants form a shear layer and the presence of a separated flow region between the shear … See more 1. ^ White (2010), "Fluid Mechanics", Section 7.1 (7th edition) 2. ^ Anderson, John D.
