The Reynolds-averaged Navier-Stokes (RANS) equations and detached-eddy simulation (DES) were used for calculating the flowfield around 6:1 prolate spheroid at angle of attack. The calculations were performed at a Reynolds number of 4.2×10 6, the flow was tripped at x/L=0.2, and the angle of attack α was varied from 10 to 20 deg. The Spalart-Allmaras one-equation model was used for the RANS calculations. Corrections for streamline curvature improve prediction of the pressure coefficient in the separated region on the leeward side of the spheroid.
