The characteristics of the mixed convection nanofluid flow inside a square enclosure saturated with porous medium are numerically investigated. The present analysis incorporates the impact of chemical reaction, Joule heating (Ohmic heating), magnetic field, and viscous dissipation. The horizontal walls of the cavity are considered as adiabatic walls. The right and left walls of the cavity are considered as cold and hot walls, respectively. The Buongiorno mathematical model is adopted to characterize the nanoliquid, and the impact of thermophoresis and Brownian motion is accounted in the present model. The equations in the non-dimensional form are solved by using the Marker-And-Cell (MAC) technique, and the outcomes are illustrated graphically. The results conclude that the magnitude of the streamline profiles decreases as the Hartmann number rises. The free convection is more dominant than forced and mixed convections. The growing values of chemical reaction parameter slightly increase the fluid flow and having a significant change in the mass transfer profiles.
