The important and new feature of study is using of non-Newtonian base fluid in nanofluid.The Titanium dioxide/0.5%wt Carboxymethyl Cellulose aqueous solution was used as nanofluid. Mixture model was used for simulation of nanofluid flow inside the micromixer. The governing equations were solved by finite volume method using a FORTRAN code. Also, in this paper new modified successive over relaxation method has been introduced to decrease the computation time, considerably. The results indicated that number of injection flows and using of baffles had significant effect on mixing index. It should be noted that the distance between baffles is an important parameter in mixing.
