摘要：

A Reynolds-averaged Navier-Stokes flow solver is used to predict the forces and moments on forebody models at high angle-of-attack rotary conditions. Cases simulated using either a circular or square ogive at an angle of attack of 60 deg, freestream Mach number of 0.21, and Reynolds number based on body diameter of approximately two million are presented and compared against wind-tunnel data from rotary testing on generic forebody models conducted by NASA Langley Research Center and the Defence Research Agency in the United Kingdom. The simulations provide insight into the flow characteristics at steady rotary conditions.
