An Approximate Method for Calculating the Minimum Suction Rate That Excludes Separation for the Boundary Layer of a Semi-Bounded Stream,

Abstract

The article discusses development of a method of calculating the lowest suction rate that would prevent laminar boundary layer separation from a curvilinear porous surface situated in a jet flow expelled from a thin slot into a slipstream. The method is based on the use of a dimensionless momentum equation for the boundary layer and of a velocity profile in the form of a fourth order polynomial. The maximum velocity at the interface between the boundary layer and the main flow is determined from an integral momentum relation for the main flow.
