Article Synopsis
- Cavitation in supercooled water was induced by short ultrasound pulses at 20 kHz, allowing for the observation of both cavitation and crystallization events using a high-speed camera.
- The study found that applying short bursts of ultrasound at moderate power significantly increased the likelihood of water remaining in a liquid state instead of crystallizing, making it suitable for assessing sonoluminescence (SL) from cavitation bubbles.
- The intensity of SL events showed a slight increase with lower temperatures, consistent with existing temperature dependence theories, while simulations suggest that bubble collapse peak temperature varies with supercooling, potentially decreasing after reaching an optimal level.
Ice crystallization in supercooled water has been initiated by focused Nd:YAG laser pulses at 1064 nm wavelength. The pulses of 8 ns duration and up to 2 mJ energy produce a bubble in the supercooled liquid after optical breakdown and plasma formation. The subsequent collapse and disintegration of the bubble into fragments was observed to be followed by ice crystal nucleation in many, but not all cases.
