Abstract: 

In current paper, exergy simulation of free convection is scrutinized. In current mathematical framework, uniform magnetic field is adopted. In order to save the time, single phase model has been involved for nanofluid. Trend of Darcy, Hartmann and Rayleigh numbers on Bejan number, exergy loss and Nusselt number are captured through figures. Obtained outputs have indicated the growth of Nuave with the Darcy and Rayleigh numbers. A growth of Lorenz forces reflects greater exergy loss. To get the desired outcomes for application prospective, lower Hartmann number should be selected.
