Synthesis and characterization of CeO2/water nanofluids and its thermal properties

In this experiment work, Cerium Oxide (CeO2) nanoparticles have been synthesized by Co-Precipitation technique from the powder mixture of Cerium Nitrate and Sodium Hydroxide (NaOH) obtained from a chemical route synthesis. Synthesized nanoparticle characterization measured by using XRD and SEM analysis. CeO2/water nanofluids with volume concentrations from 0.1%, 0.2% and 0.3% were then prepared by dispersing the synthesized nanopowder in distilled water. The experimental results have shown that thermal conductivity of the prepared nanofluids increase with the nanoparticles volume concentration. The thermal conductivity of prepared nanofluids has been measured. The experimental measurement of thermal conductivity showed a maximum enhancement of 18.10% for a volume concentration of 0.3%. The experimental results have been compared with the base fluid.
