Experimental investigation of capillary-assisted evaporation on the outside surface of horizontal tubes

Study on a compact silica gel–water adsorption chiller without vacuum valves: Design and experimental study

“…Each tray contains nine copper tubes with outside micro-grooves, which were used as heat transfer tubes in the water evaporator. Capillary-assisted evaporation is employed in these evaporators [17,18]. The copper tubes are partly immersed in the refrigerant liquid (water).…”

Performance of finned tubes used in low-pressure capillary-assisted evaporator of adsorption cooling system

“…The evaporator used air as the heat transfer fluid and due to high pressure drop, the refrigerant had to overcome the flow resistance before reaching the absorber. Capillary-assisted flow and evaporation inside circumferential rectangular microgrooves were studied by Xia et al [22,23]. They immersed a finned tube with outside circumferential micro-grooves into a pool of liquid to investigate the effects of immersion depth, evaporation pressure, and superheating degree on the performance of the evaporator.…”

“…Wang et al [24] developed an evaporator for a silica gel-water ACS based on the work shown in Refs. [22,23]. They claimed that the evaporation heat transfer coefficient was about 5000 W/(m 2 K).…”

Heat-transfer characteristics of climbing film evaporation in a vertical tube

“…Xia [27,28] mathematically and experimentally investigated the capillary-assisted evaporation inside circumferential rectangular groove. In the capillary-assisted evaporation, the liquid film outside the tube was heated by the hot fluid inside the tube evaporates.…”
