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. WebMay 5, 2024 · The cause of the bent gas jet, as a consequence of the perforation of the bubble cap, asymmetrically, is explained by plotting the velocity vectors. The effect of miscibility on the spreading dynamics of inner gas has been found to be minimal at the early stage of the bursting process. ACKNOWLEDGMENTS cindrel infotech pvt ltd
