Abstract

The coupling of a simplified version of the en transition model together with the Navier-Stokes solver EllipSys2D applied to low Reynolds number airfoil flows is described. A two-equation integral laminar boundary layer formulation was solved using a coupled direct/inverse formulation to determine laminar integral boundary layer parameters. Comparisons with the simple empirical Michel criterion and with experimentally determined transition point locations were made. A faster convergence was obtained using the e2 model caused by stable transition point location.
