【Abstract】 Heat transfer characteristics of the new surfaces were determined through temperature measurement, and the results obtained were compared with dropwise condensation studies from various sources. The differences in heat transfer between Cu-Cr and mechanical polishing surfaces were discussed. Life-time experiments were conducted on both Cu-Cr surface and mechanical polishing surface. Perfact dropwise condensation gave a life-time of over 8500 hours.更多还原
