The paper examines an approach to calculating the sonocapillary effect. The proposed model for calculating the initial sonocapillary pressure considers the temperature and density of a liquid, the capillary diameter, and the ultrasound frequency. The calculations are based on the incubation time criterion of cavitation. This approach allows us to find the threshold cavitation amplitude of ultrasound for a given frequency and to estimate the corresponding sonocapillary pressure. The calculation results show that the sonocapillary pressure is directly related to the liquid density, increasing the capillary diameter reduces the intensity of the sonocapillary effect, and a rising temperature increases the sonocapillary pressure. However, minimal experimental data are available at present to verify the obtained theoretical results. Therefore, a wider range of new experimental results should be obtained for further studies of the sonocapillary effect based on the presented results.
