- Abstract
The aim of the present study is to analyze the performance of CuO nanofluids with water as the base fluid in the flat tube bent at 90°. The analytical analysis has been performed under different Reynolds number as well as nanoparticle volume concentrations. Various thermophysical properties, that is, density, thermal conductivity, viscosity, and specific heat capacity have been estimated with well‐developed models of each, presented during previous studies carried out in the field of nanofluids. The simulation work has been performed with the help of the finite volume method. It was concluded from this study that heat transfer coefficient and Nusselt number of nanofluids at different volume concentrations between 0.1% to 0.5% v/v CuO is higher than that of the base fluids. The pressure drop obtained upon the use of nanofluids is found to be higher than the base fluid. The study also proves that nanofluids have a huge potential in playing an important role in decreasing sizes of heat transfer systems.
