摘要
空泡的动力学特性是其实现特定功能的关键。从空泡成核、生长以及溃灭3个阶段,分别介绍空泡的成核方式和基本原理、空泡生长过程中的变化以及溃灭时的能量和射流冲击。阐述环境压力、液体黏度和表面张力对空泡动力学特性影响的研究进展,并对空泡研究的重点和应用前景进行展望。
Dynamics characteristics of bubble are the key to achieving special function. The evolution of bubble contains nucleation, growth and collapse. Ways and basic principles for nucleation, the change of bubble during growth stage, and energy and shock wave in collapsing process were introduced. The effects of ambient pressure, viscosity and surface tension on bubble dynamics characteristics in latest years were summarized. The emphasis of researches and the potential applica- tions of bubble were prospected.
