Abstract

This paper presents an overview of numerical flow analyses of arbitrarily designed multi-element airfoils. Compressible unsteady inviscid flows around airfoils are analyzed by integrating time-dependent Euler equations using finite difference techniques. Numerical solutions are obtained through an explicit upwind scheme in a boundary modified square grid of Cartesian coordinates.<BR>Numerical calculations were performed on two-dimensional applications for a low-speed flow around an airfoil with variations in flap and spoiler in a wind tunnel. The pressure distributions and lift coefficients were compared with experimental data.
