Colliding droplets in turbulent flows: A numerical study

Droplets and the way they collide are at the very base of the formation of clouds and the initiation of warm rain. The evolution of a cloud droplet into a rain droplet can be classi?ed into three stages. For each stage different growth mechanisms can be identi?ed. In the ?rst stage condensation is the only effective mechanism. In the second...

Droplet collisions in turbulence

Liquid droplets occur in many natural phenomena and play an important role in a large number of industrial applications. One of the distinct properties of droplets as opposed to solid particles is their ability to merge, or coalesce upon collision. Coalescence of liquid drops is of importance in for example the food industry, where the shelf...
