Synopsis

This paper describes an experimental study of a heat pipe evacuated tube collector (ETC) with water and CuO/Water nanofluid (CWNF) for water heating application. In this study, the work is divided into three parts: fabrication of thermal system, preparation of CuO/water based nanofluids and performance analysis of thermal system. In the same parameter, a comparison of two systems was performed. Water was left in the evacuated tubes of the first system, and the second system integrated with CuO/water. The experiment was carried out with two distinct water flow rates (0.012 kg/s and 0.018 kg/s) in order to examine the thermal performance of the developed systems. For water flow rates of 0.012 kg/s and 0.018 kg/s, thermal energy efficiency of evacuated tube collector integrated with CWNF was 35.04% and 33.20%, respectively, compared to ETC with water. By improving the performance of ETC, the size of the thermal system might be reduced by 25.95%.
