Abstract

Helical turbulator has been adopted in this article, to enhance the convective flow within a pipe. Homogenous model was carried out for nanomaterial modeling. The Reynolds number (Re) and width of turbulator (b) vary from 5000 to 15000 and 5 to 15mm, respectively. Copper oxide nanoparticles were considered as an additive in to pure carrier fluid to gain better thermal behavior. Furthermore, exergy loss distributions for different cases have been reported. Outputs indicate that disturbance of the boundary layer enhances with rise of b. Mixing of core nanofluid flow and boundary layer enhances with augment of width of turbulator.
