Abstract:
The thermo-physical properties of water-based ZnO and ZnS magnetic nanofluid were measured experimentally. Appropriately, the viscosities of 0.25 wt% and 1 wt% ZnO and ZnS nanofluid were 1.03 mPa·s and 1.13 mPa·s, each greater than that of the 20°C base fluid (water), which were increased by the 7.3% and 17.7%, sequentially. The ZnO and ZnS nanofluid thermal conductivity increased from 0.605 and 0.618 to 0.654 and 0.693 W/m °C at concentrations of 0.25 wt% and 1 wt%, sequentially, when the temperature increased from the 20 to 50°C. The maximum thermal conductivity of the ZnO and ZnS nanofluid were 0.693 W/m·°C at a concentration of 1 wt% and a temperature of 50°C. Moreover, following a solar exposure of 120min, the photo-thermal energy conversion efficiency of 0.25 wt%, 0.5 wt%, 0.75 wt, and 1 wt% ZnO and ZnS nanofluids increased by 4.8%, 5.6%, 7.1%, and 4.1%, sequentially, more than that of the water.
