Cavitation Threshold Models Verified through Pulsed Sound Cavitation in Water
Some measurements of cavitation threshold by pulsed sound of 0.7 MHz were made in a 160-cm8-cell filled with distilled water, saturated by different gases.
Through a suitable definition of the experimental threshold a definite population of cavitation nuclei was available and was explored by different pulse duty ratios of the sound field. For a fixed transducer voltage the number of cavitatable nuclei, their average radius and the average sound pressure were evaluated by assuming a given theoretical threshold. So a comparison between experiment relative to many nuclei and theory became possible
