Summary

Flow fields around slender bodies at high angles of attack are investigated both experimentally and numerically including the topological analysis. Splitting of shear layer, mergence of vortices and release of large vortex cause asymmetry of flow behind high-angle-of-attack slender bodies therefore the flow asymmetry brings asymmetric side force. Effects of several parameters such as angle of attack, Reynolds number, Mach number, small asymmetry at nose configuration and nose bluntness on flow asymmetry are discussed. It is also shown that alleviation of asymmetric side force may be possible by some devices for flow control.
