Abstract

The main purpose of this research is to investigate the effect of doped nanoparticles on the thermal conductivity of nanofluids. ZnO, CuO, and Zn1-XCuXO doped nanoparticles were first fabricated by the sol-gel auto-combustion method using glycine as fuel with different molar ratios of glycine/metal ions. Different values of X = 0.02, 0.03, 0.04, 0.06, 0.07, and 0.08 were used to fabricate the Zn1-XCuXO doped nanoparticles. The X-ray diffraction patterns showed that the substitution of Zn atoms with Cu atoms was completed for X = 0.02 and 0.03, so X = 0.03 was obtained as the solubility limit for fabricating Zn1-XCuXO doped nanoparticles. The Zno, CuO, and Zn0.97Cu0.03O doped nanoparticles were then used as an additive to prepare ethylene glycol-based nanofluids with different nanoparticle concentrations. The results showed the highest observed thermal conductivity enhancement was 12.5 % and related to the nanofluid containing Zn0.97Cu0.03O doped nanoparticles at a concentration of 0.5 wt%. Moreover, adding Cu to the ZnO structure increased the thermal conductivity of the ethylene glycol-based nanofluid containing Zn0.97Cu0.03O doped nanoparticles due to its high thermal conductivity.

Graphical Abstract

Fabrication of Zn1-XCuXO nanoparticles and investigation of their effect on the thermal conductivity of nanofluids

Highlights

  • There are few reports on the use of doped nanoparticles to prepare nanofluids. So in this study, Zn0.97Cu0.03O doped nanoparticles were used as an additive to prepare ethylene glycol-based nanofluids.
  • The results showed that the thermal conductivity of nanofluids containing Zn0.97Cu0.03O nano-particles was improved.
  • The highest observed thermal conductivity enhancement was 12.5 %.
  • An advantage of using doped nanoparticles as additives in the preparation of nanofluids is enhanced nanofluid stability.
