In this numerical study, mixed convection of water/CuO nanofluid in a square enclosure with three vortex generators in different arrangements has been simulated. The lid of the enclosure is movable, and the enclosure is under the influence of a homogeneous magnetic field with Hartmann numbers of 0, 50, and 100. The horizontal walls of the enclosure are at constant temperatures Tc and Th and the vertical walls are insulated. CuO nanoparticles with volume fractions of 0-4% have been added to the base fluid. The results indicate that, by applying the magnetic field, the circulation and regular motion of the fluid become disordered. The existence of obstacles in the enclosure greatly affects the isotherms and streamlines, and this behavior is due to the disorder of fluid motion crossing among the obstacles. By reducing the intensity of magnetic field, the temperature gradients decrease and the temperature of cooling fluid dominates most parts of the enclosure. Also, by increasing the volume fraction of nanoparticles and decreasing the magnetic field intensity, the Nusselt number is enhanced.
