T0501-2-2 Characteristics of boiling on a vertically aligned SWNTs film bonded to a heated metal surface

Abstract

A vertically aligned single-walled carbon nanotube (VA-SWNT) array, which is superhydrophobic and has high thermal conductivity, was used as a heating surface to study phase-change phenomena during pool boiling. A high-speed video camera was used observe the boiling behavior and measure heat transfer properties, and the results were compared with previous measurements using a copper surface. Additionally, the boiling surface was investigated in detail by electron microscopy.
