SiC Nanofluids for Heat Transfer Applications

SiC Nanofluids for Heat Transfer Applications

011Nanofluids (NFs) are nanotechnology-based colloidal suspensions fabricated by suspending nanoparticles (NPs) in a base liquid. These fluids have shown potential to improve the heat transfer properties of conventional heat transfer fluids.

Recently, Nader Nikkan et al have used SiC nanoparticles (NPs) with different crystal structures to study thermo-physical properties of NPs. They fabricated a series of SiC NFs containing SiC NPs with different crystal structure (α-SiC and β-SiC) in a water (W)/ethylene glycol (EG) mixture (50/50 wt% ratio). Physicochemical properties of NPs/NFs were characterized by using various techniques.

The results showed that W/EG based NFs with α-SiC exhibited higher thermal conductivity (TC) than that with β-SiC. α-SiC particles have more favorable thermo-physical properties compared to the NFs fabricated with β-SiC. Besides, α1-SiC NF displayed the highest TC enhancement of 20 %, while only 14 % increase in viscosity, revealing its promising characteristics for heat transfer applications.
