The present study investigates the effect of magnetic field and internal heat generation on the free convection
flow in a rectangular cavity. Here, the cavity is filled with a porous medium saturated with
Cupper Cu–water nanofluid. The governing equations are transformed into dimensionless form in stream
function and solved numerically using finite difference method. The computations were carried out for a
wide range of the Hartmann number, solid volume fraction and magnetic field parameter. Results have
been presented in terms of the isotherms, streamlines, average Nusselt number, velocity and temperature
profiles. The obtained results are compared with the previous published work and it showed a good
agreement. It is found that the average Nusselt number decreases as the Hartmann number or the solid
volume fraction increases, while the opposite behavior occurs with the increase in magnetic field inclination
angle. Moreover, the increase in the Hartmann number leads to decrease the maximum value
of stream function, while it enhances the maximum temperature.
