Laminar flow near the break point of the surface of a prolate body of revolution
Abstract
An analysis is made of the steady axisymmetric flow of a viscous incompressible flow near the line of a slight conical break in the surface of a body of revolution at characteristic Reynolds numbers Re much greater than 1 and a body radius of about Re exp3/8. The method of matched asymptotic expansions is used to examine the solution of NavierStokes equations in the region where the boundary layer interacts with the potential flow. The boundary value problem is formulated for the viscous sublayer of the interaction region; a solution is obtained in the linear approximation. Two limiting forms of the interaction regime are found: (1) interaction on the surface of a twodimensional profile and (2) interaction in the case of flow around a body of revolution comparable in terms of thickness with the boundary layer.
