boundary-layer separation

boundary-layer separation

[′bau̇n·drē ‚lā·ər sep·ə′rā·shən]
(fluid mechanics)
That point where the boundary layer no longer continues to follow the contour of the boundary because the residual momentum of the fluid (left after overcoming viscous forces) may be insufficient to allow the flow to proceed into regions of increasing pressure. Also known as flow separation.

Different [y.sup.+]-value correspond to the differently structured near-wall regions characterized by varying pressure gradient due to alternating flow acceleration and deceleration (corresponding to the flow impingement), boundary-layer separation, post-reattachment recovery region and the newly developing attached boundary layer.
