Study of wall wettability effects on cavitation bubble collapse using lattice Boltzmann method
AIP Advances, 2021 This study investigates the effects of wall wettability on cavitation bubble collapse using the pseudopotential lattice Boltzmann method with an appropriate external force term and wall contact angle boundary condition.

Dynamics of a vapor nanobubble collapsing near a solid boundary [PDF]
, 2015 In the present paper a diffuse interface approach is used to address the collapse of a sub-micron vapor bubble near solid boundaries. This formulation enables an unprecedented description of interfacial flows that naturally takes into account topology ...

A review of bubble collapse near particles [PDF]
International Journal of Fluid EngineeringBubble–particle interactions are of great importance in cavitation bubble dynamics, especially in the case of silt-laden flow. In this paper, a review of the physical mechanisms involved in bubble collapse near particles is presented, with an emphasis on

Rippling Instability of a Collapsing Bubble [PDF]
Science, 2000 When a bubble of air rises to the top of a highly viscous liquid, it forms a dome-shaped protuberance on the free surface. Unlike a soap bubble, it bursts so slowly as to collapse under its own weight simultaneously, and folds into a wavy structure.

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 ...

Energies, 2020 In this paper, the lattice Boltzmann pseudo-potential model coupled the Carnahan–Starling (C-S) equation of state and Li’s force scheme are used to study the collapse process of cavitation bubbles near the concave wall.

Collapse dynamics of smectic-A bubbles [PDF]
The European Physical Journal E, 2006 The collapse dynamics of smectic-A bubbles are analyzed experimentally and theoretically. Each bubble is expanded from a flat film stretched at the end of a hollow cylinder and deflated through a pressure release by means of a capillary tube. Its total collapse time can be varied between 0.1s and 20s by suitably choosing the length and the internal ...
