Fighter-like vortical flow experiments/computations

The objective of this research project is to determine the ability of Euler and Navier-Stokes codes to predict vortex/shock-dominated flow that is representative of modern fighter aircraft. The motivation for this project is fourfold: (1) current fighter aircraft are capable of operating beyond C(sub L(sub MAX)); (2) high angle-of-attack vortex/shock-dominated flows are not well understood; (3) current design methods are of the trial-and-error type; and (4) current data bases are inadequate for Computational Fluid Dynamics (CFD) validation. All data and results are presented in viewgraph format.
