Prospects for the use of nanofluids in heating systems

Abstract

The desire to create new, improved working fluids for heat and mass transfer systems in the industry is gaining momentum. Now more and more researchers are being attracted to analyze the use of nanofluids in heating systems due to their improved thermal and physical properties. Nanofluids are a new type of dispersed fluids that consist of a carrier fluid in the form of which water can act, as well as polymer solutions and organic liquids, and solid particles, which are mainly particles of chemically stable metals and their oxides. The heat transfer characteristics of modern liquids are significantly improved by the addition of nanoscale solid particles with a diameter of less than 100 nm. Such liquids can be considered as promising applications in such areas as solar collectors, heat pipes, nuclear reactors, electronic cooling systems, automobile radiators, etc. The paper (publication) describes nanofluids as new energy-efficient types of working fluids for heat transfer. The most promising developments in the field of creating nanofluids from the point of view of increasing the heat transfer coefficient are presented and analyzed. Further possible promising ways of studying nanofluids are formulated.

“…Nanofluids are an emerging type of functional fluid (Guthrie et al, 2019;Malkin et al, 2019;Mustafa et al, 2019), in which nanoparticles have been proven to enhance the heat and mass transfer characteristics (Manikandan et al, 2020;Sheremet et al, 2021). These fluids have excellent application potential in refrigeration (Gao et al, 20201159), air conditioning (Said and Hassan, 2018), biomedical applications (Elahi et al, 2018), solar energy (Meibodi et al, 2016), and microelectronics fields (Sharma and Prasad, 2021).…”
