HEAT TRANSFER AND HYDRODYNAMIC CHARACTERISTICS AT EVAPORATION OF LIQUID FILM IRRIGATING A HORIZONTAL BUNDLE OF FINNED TUBES

摘要

The paper presents experimental results on heat transfer during evaporation of an R21 freon film that irrigates a packing of horizontal finned tubes. It is shown that heat transfer on the finned tubes is noticeably more intense even with respect to the full surface of the finned tube.
