Experimental Investigation of Miscible Viscous Fingering Phenomenon for Newtonian/Non-Newtonian Fluids at the Porous Media

In this paper the experimental of the viscous fingering phenomena at the interfacial of the two fluids at the porous media for Newtonian and Non-Newtonian fluids investigated. The viscous fingering challenged at the industrial/academic at the recently years. In this experimental study the porous media made with the Co2 laser technology. The water/glycerol as the Newtonian and Xanthan gum polymer used as the polymeric additive. Also, the methanol with the color used as the injection fluid to porous media cell. The experimental observation recorded and processed with the MATLAB code. The results shown that the efficiency for non-Newtonian fluid increased than the Newtonian. Also, the breakthrough time properties increased for polymeric fluid. The max position and perimeter in the porous media detected and the results shown that instability intensity of viscous fingering reduced when the Non-Newtonian used as the bulk fluid.
