Abstract

In the paper, on the basis of the three-moment equations, simple formulae for properties of a laminar boundary layer with suction are obtained. An equation relating the transition point critical Reynolds number to initial turbulence and surface roughness is presented. An approximate method for prediction of optimal suction of a boundary layer, including the main effects controlling transition of a laminar boundary layer into a turbulent one, is developed.
