Theoretical investigation and experimental support for the cavitation bubble dynamics near a spherical particle based on Weiss theorem and Kelvin impulse.

With the corresponding experimental findings as the solid support, the in-depth theoretical investigation is carried out in terms of the liquid flow field and the bubble Kelvin impulse in Then. It is estimated that: the applicability range of the Kelvin impulse theory for the bubble near the spherical particle is about the same measurementless distance between the bubble and particle is greater than 0. 50. The effect of the particle on the liquid velocity between the bubble and the particle is primarily visible in the form of the image bubble, which usually causes the liquid velocity in this region to be significantly lower than other nearby regions. with the relationship constant equal to 3. 57--7 kg, the average movement speed of the bubble centroid can be accurately predicted by establishing a strictly proportional relationship between the Kelvin impulse and the velocity.
