Detached shock wave
WebJan 1, 1974 · A DETACHED SHOCK WAVE IN FRONT OF A WEDGE OR CONE* P. I. CHUSHKIN Moscow (Received 28 March 1974) A NUMERICAL study is made of the supersonic flow past a wedge or cone with opening angles greater than limiting, when a detached shock wave arises in front of the body. WebThe solution of the approximating system is carried out numerically with different numbers of intermediate curves: in the first approximation 0V = 1) there are no intermediate curves, and S, g, t are approximated linearly from their values on the body and on the shock wave.

The transitional region in the thickness of the shock wave is in the state of non-equilibrium, where molecules collide to exchange momentum and energy between the two equilibrium states. Mott ... 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.
