Untersuchung über die Filmkondensation von Dampf bei intensivierender Einwirkung der Oberflächenkräfte

Abstract

To substantiate the geometry of finning condenser tubes for intensifying vapour condensation the dimensions of the flooding areas of the bottom part of hoizontal tubes as well as the parameters of a film flowing down in the grooves of vertical tubes are determined. The theoretical solution of the problem on vapour condensation from the profiled surfaces is presented. The experimental data on the condensation of vapours of various liquids have proved the solution obtained.
