Experimental investigation of the heat transfer performance of capillary-assisted horizontal evaporator tubes with sintered porous hydrophilic copper-carbon nanotube-titanium dioxide (Cu-CNT-TiO2) composite coatings for adsorption chiller

•A porous hydrophilic ternary Cu-CNT-TiO2 composite coating was fabricated and deposited on Cu tubes with structured external surfaces to improve the evaporation heat transfer.•A capillary-assisted evaporation heat transfer experiment using the developed tubes in a partially flooded evaporator was c...
