WebJan 25, 2024 · One of the pathways for sea spray production is through bubble bursting, which ejects myriads of droplets. We present a detailed description of the velocity of jets … WebNov 2, 2009 · We also show the formation of fine microjets, which are produced when the laser is focused inside the drop and the shock front hits small bubbles sitting under the …
WebFeb 10, 2024 · The bursting of a bubble starts with the break up of the thin liquid film that separates the air cavity from the atmosphere and ends up with the fragmentation of a rising jet. Through these two fragmentation events, bubble bursting produces film drops [6, 7] and jet drops [8–13] and constitutes one of the main sources of the ocean spray [14]. WebOct 6, 2024 · The present study compares two twin-fluid atomizer concepts based on the airflow (shock waves) pattern obtained through shadowgraph imaging for atomization of water with a low air/water pressure supply. The research work was conducted using the backlight imaging technique for converging (sonic) and converging–diverging …
