Nanofluids of PEG/MgO/SiC-H2O as Excellent Heat Transfer Medium: Synthesis, Properties and Application

Abstract

Today, one of the most significant and widely used engineering fields is heat transfer science. Saving energy and increasing efficiency are crucial given the need for energy management. Numerous sectors, including the cooling of machinery in power plants, the car industry, electronic equipment, and heat exchangers, heavily rely on fluid heat transfer. Improved design and functionality of thermal systems are made possible by increased heat transfer rate by fluids. This study presents the production, characteristics, and potential uses of PEG/MgO/SiC-H2O nanofluids as superior heat transfer media. Results indicate that when the quantity of MgO/SiC nanoparticles increased, the melting time reduced. Additionally, when the MgO/SiC NP concentration increased from 3 to 12 weight percent after 15 minutes, the reduction in melting time reached 65.5%. Additionally, when the concentration of MgO/SiC NPs was increased from 3 weight percent to 12 weight percent at photon wavelength (λ=400 nm), the electrical conductivity of PEG/MgO/SiC-H2O nanofluids increased by about 30.6%. At the same time, the absorbance increased by about 66.4% and the transmittance decreased by 58.8%.
