Detached shock wave

WebJul 1, 2013 · Hida performed an approximate analysis of detached shock waves in front of a circular cylinder and a sphere. He found that vorticity correction does not alter non-equilibrium curvature of the shock at the nose but makes its location further away from the body than in the case of non-vortical flow.
