Experimental Design by using Taguchi Method for Sensitivity Analysis of CuO/Deionized Water Nanofluid Properties

In this research, the thermal conductivity and viscosity of nanofluids has been investigated. So, the best response for the highest thermal conductivity and the lowest viscosity, respectively have been checked. For this purpose, the effect of simultaneous use of CuO/Deionized Water nanofluids to evaluate the thermal conductivity and dynamic viscosity is investigated and analyzed. The focus of the work is to investigate the influence of different transport phenomena parameters by using CuO nanoparticles dispersed in Deionized water. Given that the signal-to-noise ratio has calculated from the Larger–the better relationship, therefore, it has be concluded that the thermal conductivity of nanofluid is higher at higher volume fractions and temperatures. Finally, in this condition, volume fraction of 0.4% and temperature of 40°C will be more suitable. On the other hand, Because of the signal-to-noise ratio has calculated from the smaller-the better relationship, therefore, it has be concluded that the dynamic viscosity of nanofluid is lower at lower volume fractions and higher temperature. And also, the volume fraction of 0.1% and the temperature of 33.3°C will be more suitable.
