Identification of collapse patterns of cavitation bubbles close to a solid wall

EPJ Web of Conferences, 2013
The article describes different patterns of bubble deformation during the cavitation bubble collapse close to a solid wall for different bubble-wall distances. The bubble is generated by energy discharge in water.

Laser induced spherical bubble dynamics in partially confined geometry with acoustic feedback from container walls

Ultrasonics Sonochemistry, 2023
We investigated laser-induced cavitation dynamics in a small container with elastic thin walls and free or partially confined surface both experimentally and by numerical investigations.

Effect of wall temperature on separation bubble size in laminar hypersonic shock/boundary layer interaction flows

Advances in Mechanical Engineering, 2019
At hypersonic speeds, the external wall temperatures of an aerospace vehicle vary significantly. As a result, there is a considerable heat transfer variation between the boundary layer and the wall of the hypersonic vehicle.

Interaction of cosmological domain walls with large classical objects, like planets and satellites, and the flyby anomaly

Journal of High Energy Physics, 2022
Cosmological domain walls can be formed as a result of symmetry breaking at any epoch during the evolution of our universe. We study their interaction with a classical macroscopic object, like Earth or a satellite in Earth’s orbit.

Theoretical Modeling of Bubbling Regimes in Bubble Formation with Bubble-Bubble and Bubble-Wall Interactions

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 2008
In this study, a theoretical model for prediction of bubbling regimes in bubble formation from a single submerged orifice has been developed. The model takes into account both chamber pressure fluctuations, and bubble–bubble and bubble–wall interactions on bubbling regimes.

Ice-Water-Gas Interaction during Icebreaking by an Airgun Bubble

Journal of Marine Science and Engineering, 2022
When an airgun releases high-pressure gas underwater below an ice plate, it is observed that a bubble is formed rapidly while the ice plate is broken fiercely.

Axion interactions with domain and bubble walls

Journal of High Energy Physics
Abstract We show that interactions between axion-like particles (ALPs) and co-dimension one defects, such as phase-transition bubble walls and solitonic domain walls, can lead to important changes in the evolution of both walls and ALPs. The leading effect arises from the change in the ALP decay constant across the interface, which

Turbulence modulation of the upward turbulent bubbly flow in vertical ducts

Nuclear Engineering and Technology, 2015
The present paper aims at improving the modeling of turbulence for the upward turbulent bubbly flow through the use of experimental databases that contain data on small and large vertical ducts.

Study of cavitation bubble collapse near a rigid boundary with a multi-relaxation-time pseudo-potential lattice Boltzmann method

AIP Advances, 2020
Due to the complex phase change and heat transfer processes, the mechanisms of cavitation bubble collapse near a rigid boundary are well recognized to be complicated.
