Summary
Many energy and cooling technologies rely on boiling a liquid inside channels to remove large amounts of heat. Examples include nuclear power systems, advanced manufacturing, and electronics and data centers. Thin films of liquid form on the inside channel walls while fast-moving vapor occupies the interior of the channel. The details of liquid motion in the films can strongly affect rates of heat removal. The films can rupture in spots and then reform, which is called re-wetting. Small droplets of liquid can be ejected from the film and carried into the vapor, which is called droplet entr
