• 論文の詳細を見る

• A rotating condenser with a scraper is considered as a new means to be used in condensing heat transfer augmentation. In the previous papers, we analyzed the case where the condensate film on a vertical and a horizontal rotating cylinder was scraped off mechanically by a plate, and we clarified the condensate states and the enhancement due to scraping. In this paper, we report on the experimental results about the condensation of refrigerant R-11 corresponding to the above analysis. The distributions of cylinder surface temperatures and the mean heat transfer coefficients are obtained. The effects of speed of rotation and temperature difference between vapor and condenser surface are made clear. The enhancement due to scraping is discussed in terms of the mean Nusselt number ratio and compared with analytical results.
