Navier-Stokes investigation of blunt trailing-edge airfoils using O grids

The Navier-Stokes code is used with both the Baldwin-Lomax model and a mixing length turbulence model to investigate pressure coefficients on a typical O-grid around a blunt trailing-edge. The O-grid, instead of the more complex C-H grid, is used as the computational domain. Both models give very similar results that are at least as good as those obtained using one-equation turbulence models.
