Abstract

The aim of this paper is to answer the question: what is the state of the art when analyzing a low speed laminar airfoil with a modem Navier-Stokes program. As a test case the well-known airfoil FX 61-163 has been chosen. Two turbulence models of the program NS2D are used; a two-layer k-e model and a modification of it with an eddy viscosity limiter. A total of 111 one-night computer runs are included into this report. The computed values of lift, drag and pitching moment coefficients are compared with existing wind tunnel data as well as results from MSES Program.
