Computational Modeling of Three-Dimensional Compressible Leading Edge Vortices

Abstract

The research supported under this grant focussed on the accurate computation of compressible leading-edge vortex flows with interpretation and understanding of the results. To this end, a number of investigations were undertaken, starting with the conical Euler equation model and concluding with fully three-dimensional Navier-Stokes equation calculations. Considerable emphasis was placed on: 1) Comparisons of Euler with Navier-Stokes calculations to understand the origins of various mechanisms; 2) Comparison of calculations with experiments both to determine the accuracy of the calculations and to comprehend the physical processes; and 3) Interpretation of the results with the aid of analytical models. Keywords: Transonic cross flow, High swirl velocity.
