• 論文の詳細を見る

• A rotating condenser with a scraper is considered as a new equipment to be used in promoting the condensing heat transfer. In this report, we analyze the case where the condensate film on a rotating horizontal cylinder is scraped off mechanically by a plate. An ordinary differential equation for condensate thickness is derived with several incidental conditions, and is integrated by a numerical method. The condensate state is classified according to the combination of the conditions. The degree of enhancement due to scraping is expressed in terms of the mean Nusselt number ratio. And the effects of speed of rotation, temperature difference between vapor and condenser surface and position of scraper on heat transfer are examined.
