Effect of concentration and heat inputs on thermal conductvity of SiC/oil nanofluids

Abstract The most significant physical property responsible for heat transfer is thermal conductivity. The fluids’ thermal conductivity is improved by the addition of nano powder with better thermal conductivity, which raises the fluid’s coefficient of heat transfer. So far, there is no detailed description of the SiC nanofluid thermal conductance investigation using different base fluids (Engine, Furnace and Transformer Oils) in the literature. The primary objective of in this analysis is to evaluate SiCnan nanofluid’s thermal conductivity in various basefluids (engine oil, furnace oil and transforming oil). The tests were conducted at various temperatures of 30 °C, 35 °C, 40 °C, 45 °C, 50 °C and 55 °C on nanofluid with specific volume fraction concentrations of 0.25, 0.5, 0.75, 1.2, 1.5, 1.75 and 2. The findings showed that the thermal conductivity boosted with the rise in concentration and temperature of SiC/Engine Oil, SiC/Furnace Oil, and SiC/Transformer Oil.
