【摘要】 本文建议了一种数值计算方法，以用来计算靠近固体边界的空泡溃灭过程及对固 壁的冲击压强。与现有的方法相比，该方法具有较好的稳定性和适应性，可大大减少 计算量及占用的计算机内存。数值计算结果表明，当ε（＝Ｌ_０／Ｒ_０）＜２.０，溃灭后期 严重偏离球对称并可能形成微射流；当ε≥２．０，稍微偏离或基本保持球对称并主要 形成辐射压强；近壁空泡溃灭时，都要向固壁运动，其程度随ε的减小而增大。更多还原

【Abstract】 A numerical method for Computing the non-spherical collapse and the gene- rating impact pressure of a cavition bubble near a solid wall is suggested. By co- mparing with the existing methods,it has the advantages of being more stable and wider fitting. It can save a large amount of computing work and computer memory Computational results show that when ε=l₀/R₀（with R₀ and l₀ denoting the initi- al dius of the bubble and the initial distance from its center to the wall, respectively）, the bubble severely deviates from the spherical shape and may form a microjet. When ε≥2.0, it either almost keeps or slightly differs from thespherical shape and mainly generates radial pressure during collapsing. While collapsing,the bubble moves to the solid boundary, the smaller the ratio ε, the greater is the displacement.更多还原
