Nanofluids: properties and applications

Abstract: Nanofluids are liquid suspensions of hard nanometer-sized particles suspended in a base fluid. The suspension of small solid particles in energy transmission fluids enhances their thermal conductivity and provides an inexpensive and creative way to greatly boost their heat transfer (HT) properties. It is possible to add nanofluids to various industrial and technical issues, such as heat exchangers, electrical equipment cooling, and chemical processes. In comparison to traditional fluids utilized for HT, which include water, oil, ethylene glycol, and single nanoparticles (NPs) involving nanofluids, hybrid nanofluids are new forms of fluids that display strong HT efficiency. In terms of cooling, hybrid nanofluids function well where temperature scales are high and have a wide variety of thermal applications. In general, hybrid nanofluids are developed by diffusing two distinct forms of NPs in base fluids, which has emerged as a novel nanotechnology. [Figure not available: see fulltext.]
