Heat Transfer of Water Film Outside the Vertical Helix Tube With Hydrophilic Nanolayer
The purpose of this study is to investigate the formation of water film and its flow behavior on the surface of a vertical helix tube with hydrophilic nanolayer. The physical and mathematical models for single ingredient fluid are established and the effects of the surface geometry of the vertical helix tube on the water film flow are studied. The film thickness goes up at the trough and becomes thinner at the crest. The film thickness on the vertical helix tube with hydrophilic nanolayer is more uniform and has better heat transfer properties than the classical smooth surface tube.
