Abstract:
Copper (II) oxide /water nanofluid was prepared in two steps by using wet chemical method to prepare copper oxide nanoparticles and ultrasonic vibration for dispersing nanoparticles into de-ionized water. The characterization results show that the preparing of copper oxide /water nanofluid was successful.
The thermophysical properties: density, viscosity, Specific heat capacity and thermal conductivity were studied at different concentrations of the nanofluid (1, 2, 3 and 5) Wt%. The measuring results of the thermophysical properties show that at constant temperature; density, viscosity and thermal conductivity were found to increase by increasing the concentration of nanofluids. But the specific heat of nanofluid decreases with the increase in concentration.
The stability of the nanofluid was measured and it found that nanofluids are stable for approximately 25 days.
