Numerical investigation into the convective heat transfer of CuO nanofluids flowing through a straight tube with uniform heat flux


The turbulent flow of nanofluids with different volume concentrations of nanoparticles flowing through a straight tube under constant heat flux condition is analyzed numerically. The nanofluids considered are mixtures of copper oxide (CuO) nanoparticles and water as the base fluid. The viscosity of nanofluids is obtained on basis of experimental data. The predicted Nusselt numbers exhibit good agreement with Gnielinski's correlation. The results show that by increasing the volume concentration, the wall shear stress and heat transfer rates increase. Keywords: Nanofluid, Forced convective heat transfer, Turbulent flow, Control volume approach
