Abstract

A problem of the film type condensation of the pure vapor on disk-shaped fin is considered with taking into account the essential influence of the capillary forces. Calculations for FC-72 condensation on such fin have been performed at microgravity conditions. A hump on the condensate film thickness curve is occurred on the concave part of the fin due to the additional curvature of the disc shape. The results have been compared to results for straight fin with the same surface area of condensation. Condensate outflow from the disk-shaped film is greater than from straight fin.
