Department of Mechanical and Aerospace Engineering Seminar - Dynamics of impinging droplets on superhydrophobic surfaces

10:00am - 11:30am

The impact of liquid droplets on solid surfaces is a typical multiphase flow that has attracted much attention in both academic and industrial areas. The dynamic behaviors of an impinging droplet are highly dependent on the impact conditions: the physical properties of the liquid, the wettability of the target surface, the stiffness of the solid substrate, and the surrounding air pressure, to name a few; speaking of which, surface wettability is the predominant one over other influencing factors, and almost all impact phenomena can happen for impinging low-viscosity droplets on superhydrophobic surfaces. In this talk, I will introduce our recent studies on the impact dynamics of liquid droplets on superhydrophobic surfaces from two perspectives: 1) the effects of the liquid-solid friction on droplet rebound behaviors; 2) jet dynamics in droplet impact and its applications.
