Experimental Investigation of Falling Film Evaporation on Horizontal Tubes at Low-Pressure

Abstract:

Experimental investigation of falling film evaporation on horizontal tubes was carried out in this paper. Tube surface, spray flow rate and coolant flow rate were the factors considered in the experiment. The impact on falling film evaporation performance was obtained as expected. Experimental results are obtained that the heat transfer performances of low finned tubes are better than that of smooth tubes. The increasing of flow rate enhances heat transfer performance of falling film evaporation at first, while the flow rate gets a certain value, it will hinder the improvement of heat transfer performance. It was also found that there is almost no effects on heat transfer coefficient when the flow rate of coolant changes.
