| 摘 要： | 本文在前人研究的基础上,计入浮力、表面张力、不同流体密度比等因素对弹性膜附近气泡运动的影响,结合不可压缩理想流体理论,建立气泡与弹性膜耦合动力学数值模型,采用边界元方法进行求解,计算值与Turangan等的实验结果符合良好.通过对弹性膜附近气泡运动的数值模拟,详细分析了弹性膜两侧为同种密度液体以及不同密度液体时气泡的运动,随后又分析气泡在弹性膜和浮力的共同作用下气泡的射流特性.旨在为相关气泡与弹性膜相互作用特性的研究提供参考.

| Abstract: | Based on the previous studies,the numerical model of oscillating bubble coupling with elastic membrane is built under the consideration of buoyancy,surface tension and different fluid density ratios.Provided that the fluid around bubble is incompressible the boundary element method is adopted to solve this model and the numerical results coincide well with the Turangan's experimental results.Through the numerical simulation of the oscillating bubble near elastic membrane,the characteristics of bubble are di... |
