Using the experimental relations for approximating the effective thermophysical properties of a water/MgO-Ag hybrid nanofluid is the novelty of the present investigation in order to simulate the two dimensional MHD Casson flow past a linearly stretching/shrinking sheet with suction, radiation and convective boundary condition effects. The dual solutions along with its stability analysis are also taken into account. The Tiwari-Das mathematical formulation coupled with mass-based hybrid nanofluid model is implemented to write the governing PDEs which are then transferred to a complicated system of dimensionless ODEs with help of the similarity transformation technique. Then a well-known finite difference method with forth order accuracy in MATLAB is employed to solve them. It is proved that the selective experimental relations for effective thermophysical models must be considered more serious in the numerical modeling of hybrid nanofluids in the future. Moreover, results indicate that the range of the Casson fluid parameter for which the solution exists, enhances with radiation parameter, suction parameter and also second nanoparticle mass. Also it is shown that the magnetic field which is applied normal to the sheet results in boost up the similarity velocity profiles into the hydrodynamic boundary layer.
