Abstract
RANS/LES hybrid methods based on S-A model is presented here to simulate the separated flow of the slender under the influence of pitching oscillation at high angle of attack. The location and strength of separated vortex, flow field and pressure distribution on the surface were observed and analyzed. It is found that, the pitching oscillation at fixed frequency has strong control ability to the slender body at high angles of attack, and it would change the construction of flow field, the asymmetrical flow was restrained and tends to symmetrical flow.
