“…For acoustically driven bubble oscillators, it is reasonable to assume that the displacement of the bubble is very small (x ≪ 1) because the amplitude of the driving force is in practice usually weak (ǫ ≪ 0.1) [39,59,97]. Setting η = 3 2 , and assuming that β and γ are much greater than δ, with ǫ ≪ 0.1, the bubble oscillation can be reduced to…”

“…Studies of vibrational resonance in bubble oscillators driven by amplitudemodulated acoustic fields [59] are relatively new, although a diversity of complicated resonance patterns due to variations of amplitude and frequency, such as combination and simultaneous resonances, were reported a little earlier, involving the acoustic cavitation of bubbles under dual-frequency acoustic fields [98]. In neither of these works [59,98] was consideration given to the effect of time-delay on the bubble oscillation. Furthermore, the bubble oscillator model in [59] did not consider the impact of a phase shift between the acoustic waves.…”

Applying ultrasonic waves in liquid alloys produces refined grain structures, which is mainly contributed to ultrasonic cavitation and acoustic streaming. According to the bubbles lifetime and whether are fragmented into "daughter" bubbles, acoustic cavitation can be divided into transient cavitation and stable cavitation. As compared with the transient cavitation, the interaction between stable cavitation bubbles and solidifying alloys have been rarely reported in previous literatures. In this work, the effect of stable cavitation on the dendritic growth of succinonitrile (SCN)-8.3mol.% water organic transparent alloy is systematically investigated by high-speed digital image technique and numerical simulation. It is firstly found that when the bubble migration direction was consistent with that of dendritic growth, the periodic high pressure generated during bubble oscillation process increased the local undercooling, promoting the dendrites growth velocity effectively. Meanwhile, the concentrated stress inside dendrites induced by the linearly oscillation of cavitation bubble could break up dendrites into fragments. Specifically, if there were stable cavitation bubbles suspended around the liquid-solid interface, periodically alternating flow field and high shear force in their surrounding liquid phase was produced. As a result, the nearby dendritic fragments would be attracted to those bubbles and then transformed into spherical grains.
