Journal of Fluid Science and Technology, 2022 The generated cavitation on the NACA16-012 hydrofoil suddenly disappears at a specific angle of attack, even at a low cavitation number, where cavitation normally develops. This was named the cavitation disappearance phenomenon by the authors. It has not

Bubble Clouds: 3D Display Composed of Soap Bubble Cluster [PDF]
, 2017 We examine Bubble Clouds composed of a bubble cluster for a three-dimensional display. A bubble cluster is flexible in that its shape can be modified and it can float in the air with helium gas confinement of the bubbles. By varying the density of the bubble clusters, we project images onto the bubbles without requiring fog confinement or use of ...

Cavitation regime detection through Proper Orthogonal Decomposition: dynamics analysis of the sheet cavity on a grooved convergent-divergent nozzle [PDF]
, 2014 The unsteady character of the sheet cavity dynamics on the suction side of hydrofoils, on convergent–divergent nozzles or on blades in turbines and propellers is responsible for many issues like erosion, noise and vibrations. This two-phase flow dynamics

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 ...

Catalytic creation of baby bubble universe with small positive cosmological constant
Journal of High Energy Physics, 2019 We investigate the decay of metastable de Sitter, Minkowski and anti-de Sitter vacua catalyzed by a black hole and a cloud of strings. We apply the method to the creation of the four dimensional bubble universe in the five dimensional anti-de Sitter ...

Growth of a bubble cloud in CO2-saturated water under microgravity [PDF]
, 2020 The diffusion-driven growth of a dense cloud of bubbles immersed in a gas-supersaturated liquid is a problem that finds applications in several modern technologies such as solvent-exchange micro-reactors, nanotechnology or the manufacturing of foamy ...

The formation of a Spitzer bubble RCW 79 triggered by a cloud–cloud collision [PDF]
Publications of the Astronomical Society of Japan, 2018 AbstractUnderstanding the mechanism of O-star formation is one of the most important current issues in astrophysics. Also an issue of keen interest is how O stars affect their surroundings and trigger secondary star formation. An ${\rm H\,\small{II}}$ region RCW 79 is one of the typical Spitzer bubbles alongside RCW 120.

Liquid inertia versus bubble cloud buoyancy in circular plunging jet experiments
, 2023 International audienceWhen a liquid jet plunges into a pool, it can generate a bubble-laden jet flow underneath the surface. This common and simple phenomenon is investigated experimentally for circular jets to illustrate and quantify the role played by ...

JCMT BISTRO Observations: Magnetic Field Morphology of Bubbles Associated with NGC 6334
The Astrophysical Journal, 2023 We study the H ii regions associated with the NGC 6334 molecular cloud observed in the submillimeter and taken as part of the B -fields In STar-forming Region Observations Survey. In particular, we investigate the polarization patterns and magnetic field
