Abstract
The three-dimensional flowfield surrounding a slender body of revolution at angle of attack was solved through numerical integration of the complete Navier-Stokes equations. The leeside vortex pattern was computed for two separate sets of conditions. First, a flowfield containing laterally symmetric vortices was computed for a three-caliber ogive cylinder at Mach number 1.98 and angle of attack of 20 deg. Second, a flowfield containing laterally asymmetric vortices was computed for a cone cylinder at Mach number 1.6 and angle of attack of 30 deg. Both cases used a laminar flow assumption. All results were obtained on a CRAY-1 computer utilizing MacCormack's algorithm as vectorized by Shang. The computed results compared favorably with the two sets of experimental data used, in that all the primary flow features were captured.
