Three-dimensional shock-sulfur hexafluoride bubble interaction

AIP Advances, 2019
The evolution of shock-sulfur hexafluoride (SF6) bubble interaction is investigated using a detailed three-dimensional numerical simulation. The influences of the end wall distance on the bubble evolution are analyzed by using the high-resolution ...

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.

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.

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.

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

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.
