The F-16XL flight-test data have been used for many years in the Cranked-Arrow Wing Aerodynamics Program International series as a challenging test case for numerical prediction of military aircraft at full-scale flight conditions. The complexity of the configuration and the variety of flight-test conditions available challenge most computational fluid dynamics codes and turbulence models. This study documents the use of the Kestrel flow solver with its solution-based mesh refinement capability and delayed detached-eddy simulation turbulence models for F-16XL flight condition 25, which is a subsonic high-angle-of-attack flight condition that has proven particularly challenging for computational researchers. The spectral content of the pressure data and the integrated lift, drag, and pitching moment coefficients are also presented. The more advanced turbulence models, coupled with the more refined meshes, show very good agreement with flight-test data and reasonable resolution of the unsteady frequency content.
