The impacts of permeability and variable porosity on non-Newtonian nanofluid within flat bounded plates is considered in this work. The spatial variations is emphasised in the analysis on the behaviour of the fluid with nanofluid impact resulted in complex characteristics flow. The non-Newtonian and variable porosity reflect in the formulation of the governing equations as ordinary differential equations. The solution of these equations are obtained using Legendre collocation method which is an accurate and efficient method. The results revealed the impacts of permeability and variable porosity in the presence of joule heating on the flow, heat transfer and generally system performance providing useful insights for industrial processes dealing with non-Newtonian nanofluids particularly in a porous media. Considering comparative analysis, the results show that there is consistency with previous studies when embedded parameters are zeros.
