The combined effect of cavitation and silt abrasion presents a great challenge and threat to secure the operation and the efficiency of hydraulic machineries working in sediment-laden fluid. The present paper critically reviews the current research progress on the interaction mechanisms of the bubbles and the particles. Firstly, the analytical models including boundary treatment methods for predicting the jet dynamics of the bubble collapse near particles are demonstrated. Secondly, the bubble collapsing dynamics, jet dynamics and shock wave characteristics near particles are revealed both experimentally and numerically. Finally, the bubble-particle-wall system is investigated with a focus on microjets.
