Abstract

Surface property enhancement and boiling heat transfer characterization can be achieved through the use of nanoparticle coatings on substrates, such as graphene oxide (GO) and silver nanoparticles (AgNPs). The current investigation’s primary goal is to learn how the nanocomposite coating affects the efficiency of boiling heat transmission in pools. By manipulating the nanomaterial concentration, the dip coating approach coats aluminum substrates with AgNPs + GO nanoparticles. Coating wettability behavior, surface roughness, and morphological analysis are also recorded. Coating samples with AgNPs + GO makes them more surface rough, and the results reveal that these samples are extremely hydrophilic. If compared to coated sample to the uncoated, the critical heat flow increases by 145.76% and the heat transfer coefficient by 259.08% were observed. Additionally, the computed bubble diameter, departure frequency, and site density were shown.
