摘　　要：当空化发生在边界附近时,空化泡在生长和溃灭阶段产生的强烈射流与冲击波会对壁面造成严重影响,充分认识边界附近的空化泡动力学具有重要意义。该文从理论方法、实验研究和数值模拟等方面对边壁附近的空化泡动力学研究展开了综述。理论方面,详细综述了镜像法、Weiss定理、圆定理和保角变换等边界处理理论方法以及开尔文冲量等射流预测方法。具体而言,该文综述了各类典型边界附近的空化泡溃灭过程及理论/数值模拟预测结果,包括液滴、颗粒、壁面、狭缝以及弹性膜等;最后,对边界附近的空化泡动力学研究进行总结和展望。When cavitation occurs near the boundaries,the strong jets and shock waves generated during the growth and collapse stages of cavitation bubbles can have a serious impact on the wall.It is of great significance to fully understand the dynamics of cavitation bubbles near the boundaries.This article provides a review of cavitation dynamics researches near the boundaries from theoretical methods,experimental studies and numerical simulations.Theoretically,the boundary treatment methods such as the image method,Weiss theorem,circle theorem,conformal transformation,and the Kelvin impulse for jet prediction are reviewed in detail.Concretely speaking,the collapse processes of cavitation bubbles near various typical boundaries are reviewed together with the predictions of theoretical simulations and numerical simulations,including the droplets,particles,walls,slits and elastic membranes.Finally,the researches on bubble dynamics near the boundaries are summarized and prospected.
