Abstract

In the present work, ZnS nanofluid is prepared by two step method in water (Base Fluid) using probe sonicator. Four samples of nanofluid were prepared by altering the concentration of ZnS in water in the range 0.5 - 2 Wt.% with an interval of 0.5 Wt.%. The thermal conductivity of ZnS nanofluid is studied in the temperature range of 303-353 K. Similarly, viscosity of nanofluid is measured in the temperature range of 300-360 K for all values of concentration. There is 2.72 times enhancement in thermal conductivity is observed over the base fluid for 2 Wt.% concentration of ZnS nanofluid. The further enhancement in thermal conductivity of 2 Wt.% concentration of ZnS nanofluid is achieved by addition of Cu in ZnS nanofluid. Addition of 0.3 Vol.% Cu in 2 Wt.% concentration of ZnS nanofluid results in optimized value of thermal conductivity. This addition of Cu results in 1.20 times enhancement of thermal conductivity of 2 Wt.% concentration of ZnS nanofluids.
