Behavior of a Droplet on an Inclined Plate under Various Wettability Conditions

抄録

The aim of this study is to numerically and experimentally investigate dynamic behavior of a droplet impacting and bouncing on an inclined plate under various wettability conditions. The visualization techniques employed include Computational Fluid Dynamics (CFD) and experimental observation with a high-speed camera. The present computational model is verified for a droplet impacting on a horizontal plate. The dynamic behavior of a droplet bouncing on an inclined plate is then observed under various high-hydrophobic conditions. This paper presents some results for snapshots of bouncing motion, trajectory, the coefficient of restitution and the deformation rate at the impact on the plate.
