On the calculation of symmetric wakes. I - Two-dimensional flows
Abstract
A numerical method is proposed for calculating symmetric wakes behind two-dimensional bodies situated in laminar and turbulent incompressible flows. The appropriate thin shear-layer equations are solved, using Keller's finite-difference scheme. A double-structured numerical scheme is used at the trailing edge to account for the inner shear layer generated by the change in boundary conditions from no slip at the body to smooth flow along the symmetry axis. The Reynolds shear stress term is modeled by a modified version of the Cebeci and Smiths (1974) algebraic eddy viscosity approach. The centerline temperature distribution for laminar flow in the wake of a flat plate is calculated for various Prandtl numbers.
