Due to its low freezing point, propylene glycol (PG) is a valuable coolant in subarctic and arctic environments. Propylene glycol’s poor heat conductivity, which can be ameliorated by the inclusion of nanoparticles, is one of its limitations for energy management. In this study, probe ultrasonicating was exploited to disperse silicon carbide nanoparticles in ethylene glycol rather than a chemical process. 1.0 vol% SiC-propylene glycol nanofluid had the lowest thermal conductivity at the critical temperature. Liquid layering enhanced thermal conductivity below the temperature threshold. Brownian motion caused microconvection when the temperature was above the critical threshold. The thermal conductivity of a 1.0% SiC-propylene glycol nanofluid raised by 15.30% at a temperature of 50 °C. Below 50 °C and 1200 °C, SiC-propylene glycol nanofluid has a lower viscosity than propylene glycol. This was seen in nanofluids containing 1% and 0.10% SiC-PG by volume. SiC-propylene glycol nanofluids outperform propylene glycol as coolants for transient cooling under continuous heat flow, boosting heat transfer by 12.9% per vol%, according to our findings. Hence, propylene glycol-based nanofluids may be advantageous for energy management in achieving environmental sustainability.
