The paper "Physics of Cavitation Near Particles" by Jia-xin Yu et al. critically reviews the current research on the interaction mechanisms between cavitation bubbles and particles. The authors focus on the analytical models and boundary treatment methods for predicting the jet dynamics of bubble collapse near particles. They also explore the experimental and numerical studies on bubble collapsing dynamics, jet dynamics, and shock wave characteristics near particles. The paper emphasizes the importance of treating particle boundaries using methods such as the Weiss theorem and the circle theorem, which introduce virtual terms to account for the influence of spherical and cylindrical boundaries, respectively. The Kelvin impulse is discussed as a key tool for predicting jet directions, and the shock wave mechanisms generated during bubble collapse are analyzed, particularly in the context of cavitation damage. The review aims to provide a comprehensive understanding of the physical processes involved in cavitation near particles, which are crucial for the efficient and secure operation of hydraulic machinery in sediment-laden fluids.The paper "Physics of Cavitation Near Particles" by Jia-xin Yu et al. critically reviews the current research on the interaction mechanisms between cavitation bubbles and particles.
