Second Order Composite Velocity Solution for Large Reynolds Number Flows,

Abstract

The composite velocity procedure is applied to a reduced form of the Navier-Stokes equations where viscous effects are neglected only in the normal momentum equation. Subsonic and mildly transonic flows are considered for boattail and airfoil geometries. The composite formulation defines viscous and potential-like velocity components. These variables are coupled in a strongly implicit solution procedures (CSIP) and simulate a coupled interacting boundary layer-potential flow solver with a single system of equations. Complete second-order accurate solutions are obtained for laminar and turbulent flows where separation bubbles and weak shocks are present. The effects of inflow and outflow boundary conditions are examined and a procedure for reducing storage of the CSIP is presented. (Author)
