Multi-bubble Formation and Pressure Characterization under Mixed Injection Conditions [PDF]

open access: yesJournal of Applied Fluid Mechanics
This study investigates the bubble formation process and the associated pressure fluctuation characteristics under mixed injection conditions. The experimental findings demonstrate distinct bubble generation modes depending on the syringe size ...

Freeze/thaw-induced embolism: probability of critical bubble formation depends on speed of ice formation

open access: yesFrontiers in Plant Science, 2012
Bubble formation in the conduits of woody plants sets a challenge for uninterrupted water transportation from the soil up to the canopy. Freezing and thawing of stems has been shown to increase the number of air-filled (embolized) conduits, especially in

Numerical investigation of two-microbubble collapse and cell deformation in an ultrasonic field

open access: yesUltrasonics Sonochemistry, 2023
Two-microbubble collapse near a spherical cell in an ultrasonic field is numerically analyzed by extending a level-set method for compressible multiphase flows with bubble and cell multiple interfaces.

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

open access: yesJOURNAL 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.

Bubble Formation by Short Plunging Jet in a Continuous Casting Tundish

open access: yesMetals, 2020
A short plunging jet technique was developed to produce small bubbles in continuous casting tundish, with argon sealing, in order to promote the removal of inclusions smaller than 50 μm.

One Factor at a Time Analysis to Modify Potting Technique for Manufacturing of Bubble-Free High-Voltage Polyester Insulated Automotive Coils

open access: yesDesigns, 2022
The current study focuses on minimising the bubbles in polyester-insulated ignition coils, which were produced with a defect level of ~21–25% or 210–250 coils per 1000 batch size by using the potting method.

The Investigation of Surface Morphology Forming Mechanisms in Electropolishing Process

open access: yesInternational Journal of Electrochemical Science, 2012
As a popular application of electrochemical anodic dissolution, electropolishing is extensively adopted in the surface finishing industries of metals. Anodic dissolution is a complex reaction with many process parameters and chemical properties involved.

Enriched Air Nitrox Breathing Reduces Venous Gas Bubbles after Simulated SCUBA Diving: A Double-Blind Cross-Over Randomized Trial. [PDF]

open access: yesPLoS ONE, 2016
OBJECTIVE:To test the hypothesis whether enriched air nitrox (EAN) breathing during simulated diving reduces decompression stress when compared to compressed air breathing as assessed by intravascular bubble formation after decompression.

Evaluation of the effect of preoperative corneal curvature on the successful formation of the big bubble formation in deep anterior lamellar keratoplasty for keratoconus

open access: yesJournal of the Egyptian Ophthalmological Society, 2021
Background New approaches have been created to raise the chances of achieving big bubble (BB) in deep anterior lamellar keratoplasty (DALK); however, the BB formation is still uncertain in all cases.

BUBBLE FORMATION: A BIBLIOGRAPHY [PDF]

open access: yes, 1958
Bubble phenomena have been given a new meaning with their study in relation to the kinetic behavior of reactors. Prior to their study in relation to physics, the bulk of work on bubble phenomena concerned naval engineering problems of behavior in cavitation and water entry behavior.
