Abstract
In this paper, the statistical analysis of thermal conductivity of nanofluids containing decorated Ag nanorods with Cu nanoparticles was performed. For this purpose, Ag-Cu hybrid was synthesized and characterized using transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis. TEM studies showed that Cu nanoparticles successfully decorated the outer surface of Ag nanorods. The XRD pattern of decorated Ag nanorods with Cu nanoparticles reveals that Ag-Cu hybrid displayed both of the peaks assigned to Ag and Cu, respectively. Investigation of the effect of temperature and mass fraction on thermal conductivity of nanofluids showed that thermal conductivity of all nanofluids increases with temperature and mass fraction. The results of the statistical analysis of thermal conductivity confirm that there is a significant difference among five temperatures and three tested weight fractions for thermal conductivity of all nanofluids. However, the influence of temperature is more significant than that of mass fraction.
