    An Experimental and Theoretical Study of the Convergence of a Toroidal Shock Wave

    The convergence of a toroidal shock wave generated in a ring electric spark gap is studied experimentally and theoretically. To calculate the convergence of the internal wave, we used the Chester–Chisnell–Whit...
