Abstract

We performed wall modeled large eddy simulation of the flow field around a delta wing with sweep angle of 65 ∘ and round leading edge at angles of attack of 13∘ , 18 ∘ , and 23 ∘ . Qualitatively, the numerical simulations correctly predict the flow phenomena for all angles of attack considered. Quantitatively, the results show reasonable agreement with experimental measurements of steady and unsteady surface pressures, velocity distributions, and vortex breakdown position and frequency
