STUDY OF LAMINAR INCOMPRESSIBLE VISCOUS FLOW NEAR THE SHARP TRAILING EDGE,

Abstract

The region around the sharp corner in laminar viscous flow is studied for high Reynolds number. In order to avoid handling the full Navier-Stokes equations, the flow variables are expressed in the form of the asymptotic expansions, the first terms of which are solutions to separate local governing equations for each region. To reduce the computational details the Blasius boundary layer approaching the corner is approximated by a simple shear flow. The rotational inviscid flow region surrounding the corner becomes a well-posed boundary value problem for an elliptic partial differential equation. The thin viscous sub-layer, lying inside the rotational inviscid region, can be solved by Thwaites approximate method to calculate such parameters as skin friction and momentum thickness. In the immediate vicinity of the corner point Weinbaum's theory is used to investigate the nature of the flow. (Author)
