**5. Conclusions**

A numerical CFD work was performed to analyze the flow characteristics of Nanonon-Newtonian shear-thinning fluid inside a novel micromixer. This study outlines the hydrodynamic and thermal mixing performances for different generalized Reynolds numbers with nanofluid concentrations (ϕ = 0.5 to 5%). According to this study, the following points can be given:
