摘要

Based on the 3-dimensional N-S equations, simulation of flow field over a high-speed spinning projectile was carried out to investigate the generated mechanism of Magnus effect. Spinning was implemented through sliding mesh method. The Magnus force and moment coefficients variation with angle of attack were presented. The computation results have a good agreement with the experimental date. The generated mechanism of Magnus effect were analyzed by the flow field structure. The results show that asymmetric distortion of circumferential surface pressure and shear stress distribution, boundary layer distortion, distortional eddy generated at high angle of attack are the fundamental reasons for Magnus effect. Boat-tail has a great influence on the Magnus force and moment.
