Boiling on a Super-Water-Repellent Surface with Checkered and Spotted Coating Patterns

摘要

Boiling feature on a super-water-repellent(SWR) surface with checkered and spotted coating patterns has been studied. Bubble nucleation begins at very low superheating and the overshoot of the boiling incipience is not observed. The stable film boiling occurs in very small superheating and there is no nucleate boiling region. The bubbles generated on the surface coalesce into a vapor film without departing from the surface.
