Investigation of heat transfer during evaporation of droplets of Fe3O4 nanofluids from biphilic surfaces

Abstract In this work, unique biphilic substrates were prepared with a sharp spatial gradient of the contact angle wetting. Experimental studies process evaporation liquid droplets lying on structured surfaces have been carried out. experiment, dynamics temperature an evaporating droplet was compared depending its orientation in space. It found that suspended 0.1 wt % Fe 3 O 4 nanofluid higher and rate as to sessile droplets.
