TLDR
In this article, the use of aluminum oxide (Al2O3) doped with unmilled silicon carbide (SiCUM) nanoparticles and milled Silicon carbide nanoparticles dispersed in distilled water (DW) and ethylene glycol (EG) at 50:50 volumetric proportions was experimented in this work.Abstract:
Innovative heat elimination technologies from the radiator are needed for weight reduction in an automotive vehicle to increase the overall performance. The fluids used nowadays are based on a combination of distilled water (DW) and ethylene glycol (EG), and also using nanofluids for improving heat transfer performance has been increased within the last couple of years. The use of aluminum oxide (Al2O3) doped with unmilled silicon carbide (SiCUM) nanoparticles and milled Silicon carbide (SiCM) nanoparticles dispersed in DW and EG at 50:50 volumetric proportions experimented in this work. The focus for the important characterization of the nf which includes thermophysical properties is elaborated in this paper. The outcomes showed an optimum improvement regarding the overall thermal performance of 28.34 % making use of Al2O3 doped with milled Silicon carbide(SiCM) at a volume concentration of 0.8 %. This might be due to the size reduction of SiC nanoparticles by the milling process involved in this experiment.read more
