Abstract
Hybrid nanofluids possess better mechanical resistance, physical strength, chemical stability, thermal conductivity and so forth as compared to individual nanoliquids. Our approach in the present work is to offer a novel study involving MHD flow of hybrid nanoparticles with viscous dissipation effect through a porous medium past a stretching surface. A powerful tool of similarity transformation is utilized to transmute the governing flow model PDEs into ordinary ones. The entire system of nonlinear coupled differential equations along with boundary conditions is tackled numerically by means of Successive over Relaxation (SOR) technique. Two distinctive fluids, named Al2O3−Cu/water (hybrid nanofluid) and Cu/water (nanofluid) are exploited to lookout the parametric aspects of heat transport phenomena. Numerical data comparison with the results presented in the previous literature shows a good pact. The results obviously designate that porous medium significantly enhances the shear stresses for pure as well as hybrid nanofluids. The effect of Eckert number is to decelerate the rate of heat transportation and accelerate the temperature. Moreover, heat transport rate increases on sheet surface due to suction.
