Shock-bubble interaction
Web1 Apr 2024 · The fluid dynamics of a bubble collapsing near an elastic or viscoelastic material is coupled with the mechanical response of the material. We apply a multiphase fluid–solid coupled computational model to simulate the collapse of an air bubble in water induced by an ultrasound shock wave, near different types of materials including metals … Web1 Mar 2012 · Depending on the shock strength, the SBI may lead to ignition of the chemically reactive gases inside the bubble and will be referred to as the reactive shock–bubble …

WebIn this study, we numerically investigate the shock-induced bubble collapse phenomenon near a tissue-like material. Here, a sharp-interface model is applied to represent a 3-material system containing the liquid, the air and the gelatin. We present the results of the complex interface dynamics and compare them with the experimental data.

To … Web6 Jun 2024 · with the incident shock wave leads to the bubble deformation and the formation of liquid jet in the final stage of collapse. Higher impulsive pressure is generated in the mercury when the jet impacts the bubble surface. Also, the interactions between an air bubble and a plane shock wave in mercury in the vicinity of a glass wall are simulated.
