Splet05. jun. 2024 · Marangoni Bursting Nicole Sharp - June 5, 2024 Placing a mixture of alcohol and water atop a pool of oil creates a stunning effect that pulls droplets apart. The action is driven by the Marangoni effect, where variations in surface tension (caused in this case by the relative evaporation rates of alcohol and water) create flow. Splet11. apr. 2024 · For decades, researchers worldwide have investigated phenomena related to natural, artificial oil leakages such as oil drop formation within water bodies, their rise, and oil slick evolution after they breach the water-air interface. Despite this, the event leading to slick formation -the bursting of oil drops at the liquid-air interface has remained …

Splet17. feb. 2024 · The most significant evaporation occurs at the puddle’s shallow edges, so the surface tension at the edges becomes larger than at the center. This surface-tension difference leads to an outward fluid flow … Spleting to a Marangoni flow from the drop center outwards. The thickened rim of the drop becomes unstable and ejects a myriad of tiny droplets, which evaporate fur-ther on top of the oil bath.
