摘要：

The thermal conductivity of Er2O3/ethylene glycol (EG) nanofluids was investigated at different concentrations of Er2O3 nanoparticles in the temperature range of 20-50 degrees C. The findings showed that the volume fraction of Er2O3 nanoparticles and temperature affect the thermal conductivity. The thermal conductivity increases with increasing Er2O3 concentration and temperature, and the Er2O3/EG nanofluid showed higher thermal conductivity than the base fluid. Precise correlations are proposed to forecast the thermal conductivity of the Er2O3/EG nanofluid relative to the base fluid. These results are promising for using Er2O3/EG nanofluid in solar thermal applications.
