“…Goyer et al . 22 were able to raise the freezing temperature of supercooled water contained in tubes by about 2 K to up to 270 K by transmitting shock waves. Finally, sonocrystallization uses ultrasonic waves to freeze water.…”

Homogeneous ice nucleation needs supercooling of more than 35 K to become effective. When pressure is applied to water, the melting and the freezing points both decrease. Conversely, melting and freezing temperatures increase under negative pressure, i.e. when water is stretched. This study presents an extrapolation of homogeneous ice nucleation temperatures from positive to negative pressures as a basis for further exploration of ice nucleation under negative pressure. It predicts that increasing negative pressure at temperatures below about 262 K eventually results in homogeneous ice nucleation while at warmer temperature homogeneous cavitation, i. e. bubble nucleation, dominates. Negative pressure occurs locally and briefly when water is stretched due to mechanical shock, sonic waves, or fragmentation. The occurrence of such transient negative pressure should suffice to trigger homogeneous ice nucleation at large supercooling in the absence of ice-nucleating surfaces. In addition, negative pressure can act together with ice-inducing surfaces to enhance their intrinsic ice nucleation efficiency. Dynamic ice nucleation can be used to improve properties and uniformity of frozen products by applying ultrasonic fields and might also be relevant for the freezing of large drops in rainclouds.

“…Vonnegut [119,120] argued that the adiabatic expansions that follow compression reduce temperatures to the homogeneous nucleation limit. Shock tube measurements by Goyer et al [121] suggested that rapid compression of supercooled water causes freezing through cavitation in water droplets. Subsequent studies [122,123] do not support the cavitation conclusion, and suggest instead that supercooled water droplets in shock tubes freeze in the presence of hydrophobic surfaces.…”

“…The difference in nucleation temperature with and without the shock wave is shown to be of the order of two degrees in this case. The shock pressures used are only 0.2 atm and Goyer, Bhadra and Gitlin (1965) also speculated that to explain this effect would require this pressure to be enhanced by cavitation. …”
