(fluid mechanics)
Control over the development of a boundary layer by reduction of surface roughness and choice of surface contours. Abbreviated BLC.

boundary-layer control

boundary-layer control
Flow pattern without boundary layer control.
boundary-layer control
Flow pattern after high-velocity air is blow over the airfoil.
boundary-layer control
Aircraft with boundary layer control by blowing.
Methods used to control the boundary layer by sucking air through slots, making a series of small holes or porous surfaces, by blowing, or by using discrete jets. These methods can be employed to decrease drag or to increase lift on the whole or part of the surface.
