Falling film heat exchanger
WebAbstract. Falling film heat exchanger includes circular areas for evenly distributing feed liquid and/or heat exchange liquid to the tube interior and/or exterior surfaces. The circular areas may be defined by a liquid porous material, slots in an O-ring or vertical slots in the holes through and to which the tubes are joined. WebSep 18, 2024 · Abstract. The performance of a falling-film heat exchanger is strongly linked to the surface characteristics and the heat transfer processes that take place over the tubes. The primary aim of this numerical study is to characterize the influence of surface wettability on the film flow behavior and its associated surface heat transfer in the jet …
