Simulations of a bubble wall interacting with an electroweak plasma [PDF]
Journal of High Energy Physics, 2021 Abstract We perform large-scale real-time simulations of a bubble wall sweeping through an out-of-equilibrium plasma. The scenario we have in mind is the electroweak phase transition, which may be first order in extensions of the Standard Model, and produce such bubbles.

Numerical Study on the Rising Motion of Bubbles near the Wall
Applied Sciences, 2021 Based on the volume of fluid method (VOF), the rising characteristics of bubbles in near-wall static water are studied. In this study, the influence of the wall on the rising motion of the bubble was studied by changing the distance of the bubble wall ...

Dynamic behaviour of cavitation bubble close to a flexible wall [PDF]
EPJ Web of Conferences, 2022 The dynamic behaviour of cavitation bubble close to a flexible boundary is investigated experimentally. The cavitation bubble is produced as a consequence of an optical breakdown generated by the focus of 532 nm Nd-Yag laser beam.

Morphological Analysis of a Collapsing Cavitation Bubble near a Solid Wall with Complex Geometry
Applied Sciences, 2023 The interaction mechanism between the cavitation bubble and a solid wall is a basic problem in bubble collapse prevention and application. In particular, when bubble collapse occurs near solid walls with arbitrarily complex geometries, it is difficult to

Simulation and analysis of collapsing vapor-bubble clusters with special emphasis on potentially erosive impact loads at walls [PDF]
EPJ Web of Conferences, 2018 Cavitation is a process where a liquid evaporates due to a pressure drop and re-condenses violently. Noise, material erosion and altered system dynamics characterize for such a process for which shock waves, rarefaction waves and vapor generation are ...

Analysis of doublet bubble dynamics near a rigid wall in ferroparticle nanofluids
Case Studies in Thermal Engineering, 2022 This study aims to characterize the interaction of doublet bubbles growing near a solid wall in ferroparticle nanofluids. Accordingly, we analyzed the behavior of spherical bubbles near a rigid wall considering liquid compressibility of suspended ferro ...
