中文摘要	基于FLUENT软件环境,采用VOF模型和非稳态方法求解Navier-Stokes方程,模拟了近壁面的空泡溃灭过程,同时计算了空泡溃灭处与壁面的距离对射流强度的影响.结果表明:在近壁面,空泡将形成非对称溃灭,因水锤作用,引发高速水射流在壁面产生高压而形成空蚀破坏;基于FLUENT环境的计算结果与已有的实验和计算结果相符,为研究空泡溃灭和空蚀机制提供了类比的数值计算方法.; Volume of Fluid(VOF) model and unsteady method were used to solve the Navier-Stoles equation to simulate the bubble collapse process using FLUENT software.The simulation results show that the asymmetric collapse occured on the spherical bubble near a solid wall.The following micro jet then caused high pressure domain on the solid wall to induce the cavitation erosion based on the water hammer theory.The distance between the bubble and the solid wall was also proved to play important role in the erosion.The numerical results coped with the existed experimental and numerical results,and this software provided a platform for the numerical calculation on cavitation erosion.
