Original abstract
The goal of the paper is to introduce liquid film formation and heat transfer on the bundle of horizontal tubes in atmospheric pressure. The investigations were done for different types of the tubes surface structure, namely smooth surface tubes, ribbed tubes, fin tubes. The work is focused on water falling film in atmospheric pressure were the film formation is accompanied with phase change. The paper presents results of parametrical studies focused on expression of horizontal tube spacing and falling liquid flow rate influence on falling film formation and heat transfer. Due to the complexity of the problem the research was done experimentally on an experimental set-up with a bundle of horizontal replaceable tubes.

Příspěvek představuje tvorbu kaplaného filmu na trubkových svazcích a přestup tepla na horizontálních trubkách uspořádaných v kompaktní svazek. Práce je zaměřena na experimentálním hodnocení trubek s různou povrchovou strukturou vnějšího povrchu, konkrétně hladké trubky, pískované trubky, rádlované trubky a trubky s mikrožebry.
