Abstract

The boiling feature on a super water-repellent (SWR) surface has been studied. The SWR surface has a coating layer of fine particles of nickel and PTFE. Its contact angle to water is 152° in room temperature. The heat transfer surface is facing upward, and the diameter of the heated section is 17 mm. The boiling feature of this surface is completely different from that of usual surfaces. 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. The stable vapor film exists even at a surface temperature below the saturation temperature.
