“…In the gas behind the wave, along with the incident sound wave, the reflected sound wave and the and entropy-vortex wave occur (and a ripple occurs on the very surface of discontinuity) [9] (an analog of the Marangoni wave, see [10] and [11]). According to the results of [10] and [11], one can state that, in the two-dimensional case, the bifurcation of a critical stable shock wave leads, at a first stage, to intermittency (a band structure), and then, a ripple of an analog of the Marangoni wave occurs on the very surface of discontinuity, and this ripple generates jets shedding from the front the shock wave (an analog of dendrites in crystallization, see [10] and [11]).…”
