WebNASA/ADS The dynamics of jets produced by bursting bubbles Popinet, Stephane Deike, Luc Zaleski, Stéphane Seon, Thomas Abstract Sea spray is the main source of aerosols above the ocean. One of the pathways for sea spray production is through bubble bursting and ejecting myriads of droplets. WebNov 27, 2024 · Bubble bursting is important in air–sea interactions, food science, and industry, but the process of the pressurized gas escaping from inside the bursting bubble is not well understood.

WebThe movement of the jet gradually tears the bubble into several annular bubbles. The collapsed bubble is different from the closed cavity in that there is an upward jet at the bottom when the closed cavity collapses, and no apparent bottom jet is produced at the bottom of the bubble when the bubble collapses after the bubble is reclosed. WebWe present a detailed description of the velocity of jets formed by bubble bursting, obtained through extensive comparison between experimental results and numerical …
WebDec 11, 2024 · We also show that some entrapped bubbles on inclined surfaces would move to the droplet surface and eventually burst, shooting out another thin jet. The correlation between the jet velocity and the bubble size is compared with different empirical scaling laws in the literature. ACKNOWLEDGMENTS
