| Research Abstract |
Fundamental knowledge of condensation from steam-air mixtures onto a single horizontal copper tube was experimentally studied by using a horizontal copper tube. The effect of condensate dripped from upper tubes on the condensation heat transfer was also investigated. Several methods for heat transfer augmentation, e. g. water-repellent finishing, finned tubes and mini-tubes, were tested and the efficient knowledge for the development of high-performance condensers adopted in the future power plant had been developed.
