The study of the dynamic impact of a liquid on a solid surface was invented by Worthington. This study is a key element of a wide variety of phenomena encountered in industrial applications. In recent years, some research groups have begun to study the impact of water droplets on superhydrophobic surfaces. Several experimental parameters affect the dynamics of impact including wettability, roughness, impact velocity, surface tension, liquid density and viscosity.
In this work, we will try to establish a correlation between the intrinsic parameters of the impacting micro-drop (diameter and speed) and the morphology of the surface. Elastic materials including silicone will be used.
Using a high speed camera and incorporating a set of surfaces (with different structures), the process of impacting water droplets with varying impact velocities on surfaces will be monitored. Using image processing techniques, analytical investigations and machine learning, the behavior of the water drop on superhydrophobic surfaces as a function of surface structures will been predicted and quantified.
