%X In this paper, the magnetohydrodynamic mixed convection flow about an isothermal cone embedded in a saturated porousmedium is considered. The Darcian model including the viscous dissipation effects in the energy equation is used. Thegoverning equations are transformed by using a set of nonsimilarity variables and solved by using Keller box method. Theentire mixed convection regime is covered by nonsimilarity parameter ¦Ö, where ¦Ö=0 corresponds to pure free convection and¦Ö=1 corresponds to pure forced convection. Numerical results for the dimensionless velocity and temperature profiles and thelocal Nusselt number for various values of the mixed convection parameter ¦Ö, the cone angle parameter m, the magnetic fieldstrength parameter H, and the modify Gebhart number Ge* are drawn. It is found that increasing the magnetic strengthdecreased the heat transfer rates, while increasing the cone angle increased the heat transfer rates.
