Magneto-convective flow through a porous enclosure with Hall current and thermal radiation effects: numerical study

This paper reports the numerical study of magnetohydrodynamic radiative-convective flow in a square cavity containing porous medium with Hall currents. is relent to hydromagnetic fuel cell design and thermofluidic dynamics complex magnetic liquid fabrication enclosures. The governing equations this fluid system are solved by finite-difference vorticity stream function approach executed MATLAB software. A detailed parametric investigation impact Rayleigh number (thermal buoyancy parameter), Hartman (magnetic body force Darcy (permeability parameter radiation on streamline, temperature contours, local Nusselt along hot wall mid-section velocity profiles computed. Validation previous special cases literature included. current radiative effects found significantly modify characteristics. From results, it that field suppresses natural convection only for small ratios. But, larger ratio, effective suppressing thermal convective flow.
