Abstract: 

A numerical analysis of Copper oxide-H2O nanomaterial hydrothermal characteristics through a duct with utilizing turbulator under constant heat flux has been carried out by means of FVM. Simulations contain the effect of width tape (b) and Reynolds number (Re). Single phase model for nanomaterial and k-ɛ for turbulence modeling have been selected. Outputs indicate that friction factor tends to decline with augment of Re. Greater Nu due to insertion of turbulator is related to swirl flow generation. Augmented convective heat transfer is obtained with inserting turbulator with higher width.
