R-113 condensation on vertically finned plate

핀이 가공된 수직평판의 R-113 응축

In this study, condensation tests were conducted on a vertically finned plate (fin height 1 mm, fin thickness 1 mm, fin spacing 1 mm) using R-113. Results showed that fins enhanced the condensation on a vertical plain surface as much as four times. Comparison with theoretical models revealed that the effect off surface tension should be included in the model. The effect of interruption plates was also investigated. The plates were not effective in enhancing the finned plate condensation. The reason may be attributed to the already thinned condensate film on the finned surface.
