Abstract
Abstract This study investigates turbulent heat transfer performance (HTP) and entropy production rate (EPR) of CuO/H 2 O nanofluid flowing through Bessel‐like converging pipes. The effects of Reynold's number , nanoparticle volume ratio , and convergence index on the hydrodynamic, HTP, and EPR were examined. The results show that an increase in the convergence index enhances pressure drop, Nusselt number, and viscous EPR. However, the opposite is the case for the thermal EPR. Furthermore, the multiobjective optimization of pressure drop, Nusselt number, and EPR show that both Nusselt number and pressure drop attained the optimum value simultaneously.
