The Comparison between the Performance of Water and CuO/Water nanofluid in Improving the Heat Transfer of Small Spaces

Abstract

This paper examines the design of heat exchanger made of copper pipe for cooling small space system and the effects of water and CuO/distilled water like coolants channeling inside the heat exchanger to increase the transportation of heat between the compartment and the heat exchanger and comparison between them. The nano-fluid was prepared by dispersing a nanoparticle (CuO) in base fluid (distilled water). Nano-fluid with a nominal diameter of 50 nm at volume frictions (0.27 vol. %) at compartment temperature was used for these investigations. The analysis showed that secondary cooling system by means of nano-fluid (CuO/distilled water) has advantages in enhancing the flow rate heat transfer, best from base fluid (distilled water) also in Nusselt number.
