Experimental, analytical, and numerical study of droplet impact on a horizontal fiber

The experimental study and volume of fluid numerical simulation are performed to study the capturing mechanism of liquid droplets in fibrous filters. The study is done by focusing on the single droplet impact on a horizontal fiber. In the meantime, analytical expression based on the energy balance method incorporating the effect of variation of wall adhesion and droplet eccentricity is developed for the threshold capture velocity of the droplet....
