Marangoni flow of Binary Mixtures on a Liquid Layer
Posted by Chengxi Zhao
Here is an interesting article about Marangoni Bursting. This is the link of the Youtube video. In this work, researchers focused on the instability observed when a two-component drop of water and volatile alcohol was deposited on a bath of sunflower oil. The drop temporarily spread and spontaneously broke up into thousands of tiny droplets. They also demonstrated that Marangoni flows induced by the evaporation of alcohol played a key role in the overall phenomenon.
