Abstract:

This paper describes recently-developed conformal mapping techniques applicable to cases involving general multielement airfoils having any number of airfoil elements. Each technique can be considered as a purely geometric construction or, equivalently, as a network a streamlines and potential-lines of an auxiliary potential-flow solution. The nonuniqueness of such solutions ensures the existence of a wide variety of conformal grid types, each having different point-spacing characteristics. A chronicle is given of the search for the type of grid most suitable for solving the inviscid compressible flow equations using a distributed-source field-panel approach. Examples are shown for grids involving up to four airfoil elements.
