Abstract

Two-dimensional Navier-Stokes computations have been carried out on the FX 66-17AII-182 airfoil using the ns2d code. The computational four block structured grid was created with the Icem Mulcad mesh generator taking into account the airfoil finite thickness trailing edge. A two-layer k-e turbulence model was employed in the computations with an empirical transition prediction model. Computations were performed at Reynolds numbers 1.5 and 3 million in 64 cases altogether. The computed lift, drag and pitching moment coefficients are compared with existing wind tunnel data.
