MODELING OF FREE SURFACE FLOWS: UNDERSTANDING FALLING DROPS

摘要：

Our study deals with the understanding of drop dynamics during partial coalescence. When liquid 1 drop falls through liquid 2 to eventually hit the liquid 2-liquid 1 interface, its initial impact on the interface can produce daughter droplets of liquid 1. Results show that inertia and interfacial surface tension forces largely govern the process of partial coalescence. Below the specified lower bound and above the specified upper bound, the partial coalescence is suppressed by the viscous force and gravity force, respectively. The process of partial coalescence is also observed for multiple drop impact where the process of pinch off is different.
