"Boundary layer control refers to methods of controlling the behaviour of fluid flow boundary layers. It may be desirable to reduce flow separation on fast vehicles to reduce the size of the wake (streamlining), which may reduce drag. Boundary layer separation is generally undesirable in aircraft high lift coefficient systems and jet engine intakes. Laminar flow produces less skin friction than turbulent but a turbulent boundary layer transfers h… " - Boundary layer control blc

WebOct 1, 2000 · 3.1. Boundary layer control (BLC) Boundary layer (or flow) control, as a means of preventing separation, has traditionally been associated with the injection of fluid to, or the removal of a fluid from, a boundary layer; or the motion of a surface in the general direction of the stream (e.g. [60], [61] ).
