液体中气(或汽)泡在变压力场中的生长与崩溃现象导致固体材料的剥蚀,并向外辐射出强烈的空化噪声.研究泡的运动机制是一项重要的工作,文献[1]中介绍了几种泡壁运动方程式,基于不可压流体假设的Rayleigh 方程在大的泡壁运动马赫数下是不适用的,Gilmore 方程中对可压缩性的影响作了考虑.Lastman & Wentzell 作了进一步研究,指出Gilmore 方程在大马赫数场合的应用中存在问题,因此,关于可压缩性的处理还存在争议.
The growth and collapse of gas (or vapor) bubbles in a fluid pressure field lead to denudation of solid materials and the intense cavitation noise radiated outwards. The study of bubble motion mechanism is an important work [1] ] Introduced several bubble wall equations of motion, the Rayleigh equation based on the assumption of incompressible fluids is not applicable at large bubble wall Mach numbers, and the effect on the compressibility in the Gilmore equation was taken into account.Lastman & Wentzell After further research, we pointed out that the Gilmore equation has some problems in the application of large Mach number. Therefore, there is still controversy about the compressibility.
