THE ENERGIES AND PRESSURES OF ACOUSTIC TRANSIENTS ASSOCIATED WITH OPTICAL CAVITATION IN WATER

The acoustic transients associated with optical cavitation in water have been studied using a high-speed interferometric technique. Radial pressure profiles of these spherical transients have been obtained over a range between 2 and 22 mm from the centre of the cavity. Pressure-radius relationships and transient energies have subsequently been determined for the acoustic waves and the volumes of liquid enclosed within them. © 1990 Taylor & Francis Ltd.
