Abstract : The current work investigates the flow problem of viscous two-phase dusty nanofluid containing Al2O3 and heat transfer through a Riga plate embedded in a porous media in the presence of Newtonian heating. The governing partial differential equations are transformed into ordinary differential equations using appropriate similarity variables and numerically solved using the fourth-fifth order Runge–Kutta (RKF-45) method with a shooting approach. Further, Graphs are shown to demonstrate how the constraint varies on different profiles. Result reveals that the dust phase velocity declines faster than fluid phase velocity for improved volume fraction. Improved values of modified Hartmann number will enhance both dust and fluid phase velocity and temperature. For increasing levels of the heat source/sink parameter, the fluid phase exhibits increased heat transfer near the wall and improve quicker than the dust phase. As the width of magnets and electrodes increases, the heat transfer decreases faster than the fluid phase. Increases in the values of the heat source/sink parameter and the Eckert number enhance the heat transfer rate for Newtonian heating cases but decrease it for common wall temperature cases. Improved values of porosity parameter will decline the surface drag force.
