Originální abstrakt

In this paper, an experimental research of the heat transfer of water falling film on a tube bundle is presented. First part states current knowledge review which is focused on the problematic falling liquid mode. This mode is significant for the heat transfer characteristics of the film and wetting. Subsequently the paper is concentrated on the essential transition criteria such as Galileo, Reynolds and Nusselt number. Experiments examine the local heat transfer coefficient behavior in an low-pressure environment formed in the heat exchanger chamber by vacuum pump. This research has positive results for the development of main components (heat exchangers for condensation and evaporation) in absorption units.
