MHD FLOW OF Cu-Al2O3/WATER HYBRID NANOFLUID THROUGH A POROUS MEDIA

Hybrid nanoliquids comprise of better physical strength, mechanical resistance, thermal conductivity, and chemical stability as equated to individual nanoliquids. In this paper, MHD hybrid nanoparticle flow with heat and mass transfer attributes is numerically investigated. Flow is taken over a stretching surface embedded in a porous medium. The governing flow model partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs) using a powerful tool of similarity transformations. The relevant system of differential equations and boundary conditions are numerically treated with the successive over-relaxation (SOR) technique. Heat and mass transfer features of both pure and hybrid nanofluids are examined for the preeminent parameters. Our results are associated with the previously accomplished numerical and experimental results and found to be in good agreement. It is profound that the thermal radiation phenomenon reduces the heat transport rate, while the chemical reaction increases the mass transfer rate. The outcomes evidently designate that the shear stresses for pure as well as hybrid nanofluids are increased on the sheet surface with the impact of porosity parameter.
