Composition by collision of two falling droplets

Abstract

A novel droplet generator equipped with flow-control has been developed for the formation of various liquid droplets. Two fast falling droplets with small angle are collided in air and are formed one droplet, which gets out of its shape from various type of oval to ball in falling by convection inside a small droplet. On the other side, two water jets with same speed and same angle are collided. But, one jet cannot be obtained by collision.
