Child droplets from micro-explosion of emulsion and immiscible two-component droplets [PDF]
International Journal of Heat and Mass Transfer, 2021 Abstract Here we present the experimental findings of the research into the integral characteristics of secondary droplets produced from the micro-explosive fragmentation of two types of initial droplets. Both types are based on water and tetradecane: an emulsion droplet and a two-component immiscible droplet with water as the core and tetradecane as
