However, for stronger shock diffraction, they do not cross each other and are corresponding to the Mach reflection. In the vicinity of the gasdynamics focus, the high pressure and density gradients induce a series of vortex pairs as observed. By plotting the trajectories of the triple points during the shock wave focusing, the dynamics of the different types of the reflection and diffraction can be explained.
