NUMERICAL INVESTIGATION OF THE MECHANISM FOR ASYMMETRIC VORTEX FLOWS

A robust iterative method suitable for the numerical simulation of high angie-of-attack vortex flows is established based upon the multiple line-vortex method (MLVM). With given symmetric or asymmetric locations of separation lines, the first converged solution at angle of attack as high as 60?is obtained by using the present method. Numerical experiments for a tangent-ogive forebody indicate the viscous onset mechanism of asymmetric vortex flows over body of revolution at high angles of attack and zero sid...
