Single phase based study of Ag-Cu/EO Williamson hybrid nanofluid flow over a stretching surface with shape factor

Hybrid nanofluids is the suspension of twodifferent types of nanoparticles in the base fluid. This enhances the heat transfer capabilities of the ordinaryfluids and prove to better heat exponent as compare to the nanofluids. In this research, we investigate the nanofluid for its flowand heat transport features by subjecting it to a slippery surface. Thefluidmotion disturbance is achieved by with the utilization of nonlinear, uniformhorizontal porous stretching of the surface with in aDarcy type porous media. The effect of nanoparticle shapes, porous medium, variable thermal conductivity and thermal radiation are also included in this analysis. Anumerical method, Keller box is used to find the self-similar solution of equations. Two different types of nanoparticles, Copper(Cu) and Silver(Ag) with non-Newtonian Engine Oil (EO) based fluid have been taken into consideration for our analysis. The valuable finding of this study is that the comparative heat transfer rate of Williamson hybrid nanofluids (Ag-Cu/EO) graduallymore increases as compared to conventional nanofluids (Cu-EO). Moreover, Lamina-shaped particles result in themost significant temperature in the boundary layer, while the lowest temperature is observed in spherical-shaped nanoparticles. Finally entropy of the system exaggerateswith the incorporation of nanoparticle percentage by volume, thermal radiation, variable thermal conductivity andWilliamson variable.
