Analysis of the film condensation process of vapor on a vertical finely serrated surface

  • 26 Accesses

Abstract

The process of film condensation of vapor on vertical finely serrated surfaces is investigated. The analysis shows that owing to the specific conditions under which the distribution of the condensed film along the cooling surface is in the main affected by surface tension, the effectiveness of such surfaces may be several times higher than that of plain tubes.
