The capabilities of a Navier-Stokes solver to predict the friction drag over an airfoil were studied. In particular, the sensitivity to the grids resolution and to different Reynolds-averaged Navier-Stokes equations (RANS) closure models was investigated for three different Reynolds: the standard κ-ε, Renormalization Group (RNG) κ-ε, and Reynolds stress model. The results indicate that in general, the RANS calculations seem to require computational resources, both memory and computing time.
