Investigating non-Newtonian nano-fluid flow based on first and second law of thermodynamics by micro-annulus

In this study first and second law analyses of non-Newtonian nano-fluid flow through an annular cylinder filled with water- CMC/TiO2 by considering temperature jump slip velocity were investigated numerically. The single-phase was developed for heat transfer flow. impact Reynolds number, nano-particles volume fraction, jump, on Nusselt numbers entropy generation evaluated the findings discussed performance working fluid. indicate that note higher shear rate in presence interior wall number than outside walls. According to shear-thinning fluid behavior, when has a rate, apparent viscosity would be small. So, it can concluded close inner low which decreased force improved due convection-advection phenomena. addition, showed ratio is very high at entrance along tube. Furthermore, increases nano-particle fraction.
