On the mechanism of droplet rolling and spinning in inclined hydrophobic plates in wedge with different wetting states

Abstract A water droplet rolling and spinning in an inclined hydrophobic wedge with different wetting states of wedge plates is examined pertinent to self-cleaning applications. The droplet motion in the hydrophobic wedge is simulated in 3D space incorporating the experimental data. A high-speed rec...
