Аннотация

Results of an experimental investigation of heat transfer during condensation on finned tubes with rectangular fins are presented. Experiments were carried out on freon-12 at saturation temperatures of 20, 40 and 70 C. It has been found that during condensation on finned surfaces, in which the distance between the fins with relation to the capillary constant of the liquid is less than one, the bottom part of the finned tube is covered by a constantly retained condensate layer. The height of the layer coincides with the height of the capillary rise in an infinite vertical slit of the same width. Considerable (up to threefold) change of heat transfer depending on the dimensionless distance between the fins is established.
