Thermal Conductivity Analysis and Characterization of Copper Oxide Nanofluids through Different Techniques

Abstract

The aim of this research is to analyse the thermal conductivity of copper oxide (CuO) nanofluids. In the present study CuO nanofluids were prepared using a new method of wet chemical method and the testing was carried out by various techniques. X-Ray Diffraction (XRD) pattern was used to determine the crystal structure and the average crystallite size of the CuO nanofluids. Scanning Electron Microscope (SEM) and Transmission Electron Microscopy (TEM) were used to study the morphology and the particle size. Similarly Dynamic Light Scattering (DLS) was used to estimate the size of the CuO nanofluids. Finally UV-Visible absorption spectrum was used to measure the optical property of the CuO nanofluids. The thermal conductivity of CuO nanofluids was analyzed using KD2 Pro thermal property analyzer and concludes that the thermal conductivity is increased with the increase of particle loading.
