EULER CALCULATIONS FOR MULTIELEMENT AIRFOILS USING CARTESIAN GRIDS.

A finite volume formulation for the Euler equations using Cartesian grids is presented and used to study complex two-dimensional configurations. The formulation extends methods developed for the potential equation to the Euler equations. Results using this approach for single-element airfoils are shown to be competitive with, and as accurate as other methods that employ mapped grids. Further, it is demonstrated that this method provides a simple and accurate procedure for solving flow problems involving multielement airfoils.
