Abstract
The effects of surface tension on the condensation phenomena become more remarkable as a site where vapor condense is smaller. From a view point above, a pollutant removal system which utilizes such a peculiarity of condensation phenomena in a small scale system may have higher efficiency. As a means of investigating the promotion mechanism systematically, the characteristics of condensation heat transfer on a horizontal slender tube with a tininess diameter was investigated experimentally. As a result, it was clarified that the optimum conditions exist where the heat transfer ratio is maximum.
