Abstract:

The relationship between cavitation nuclei size and transient cavitation thresholds was studied employing an apparatus designed to perform automated threshold measurements using sound emission and sonoluminescence as transient cavitation indicators. Experimental results agree with crevice model predictions based on either the crevice or free bubble nucleation models. Observed deviations may be due to limitations in the theories or systematic experimental errors.
