The current study conducts analyses of the rst and second laws for non-Newtonian nano- uid ow through an annular cylinder lled with non-Newtonian water-CMC/TiO2 nano- uid, considering temperature jump and slip velocity. A single-phase pattern was developed for heat transfer and nano- uid ow. To this end, the impacts of Reynolds number, volume fraction of nano-particles, temperature jump, and slip velocity on the Nusselt numbers and entropy generation were evaluated and the ndings on the non-Newtonian performance of the working uid were reported. According to our ndings, due to the higher shear rate in the presence of the interior wall, the Nusselt number of the interior wall was higher than that of the outside walls. Based on the shear-thinning uid behavior, in case the ow has a higher shear rate, its apparent viscosity would be small. Therefore, it can be concluded that the apparent viscosity of the ow close to the inner wall is low, which reduces the impact of viscosity force and improves heat transfer due to convection-advection phenomenon. In addition, the ndings illustrate that the entropy generation ratio is very high at the entrance and decreases along the annular tube. Furthermore, the apparent viscosity of uid increases by nano-particle volume fraction. © 2022 Sharif University of Technology. All rights reserved.
