A rotating condenser with a scraper is considered as a new method used in condensing heat transfer augmentation. In the previous papers, we analyzed the case where the condensate film on the vertical and the horizontal rotating cylinder was scraped off mechanically by the plate, and we clarified the condensate states and the enhancement due to scraping. In this paper, we report the experimental results for the condensation of R-11 corresponding to the above analyses. The distributions of cylinder surface temperature 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 arranged in terms of the mean Nusselt number ratio and compared with analytical results.
