Boundary layer separation — is when the thin layer of viscous fluid leaves the surface of the body that it is flowing over. The viscosity of the fluid causes the boundary layer separation. [Wilcox, David C. Basic Fluid Mechanics. 3rd ed. Mill Valley: DCW Industries, Inc.,… … Wikipedia
Boundary layer suction — is technique in which an air pump is used to extract the boundary layer at the wing or the inlet of an aircraft. Improving the air flow can reduce drag. Improvements in fuel efficiency have been estimated as high as 30%. The boundary layerThe air … Wikipedia
