Interaction between a boundary layer and external flow in the case of longitudinal flow past bodies of revolution
Abstract
The interaction of external longitudinal flow with a laminar boundary layer on the surface of a cylinder is investigated in the context of the asymptotic theory of stationary flows of an incompressible viscous fluid at large Reynolds numbers, assuming that the layer thickness is greater than the cylinder curvature radius. A solution is obtained by using asymptotic expansions of the unlimited kind. It is shown that, depending on the ratio between the cylinder radius and the boundary layer thickness, the longitudinal dimension of the interaction region may be greater, comparable with, or smaller than the thickness of the boundary layer. The boundary layer problem for the viscous sublayer of the boundary region is formulated.
