    Abstract:

    This paper numerically investigates thermomagnetic convection of air in a porous cubic enclosure with a electric coil inclined around the X axis under microgravity environment. The porous cubic enclosure is heated isothermally from left-hand side vertical wall and cooled isothermally from opposing wall while the other four walls are thermally insulated. The governing equations in primitive variables are discretized by the finite-volume method and solved by the SIMPLE algorithm. Computations were performed for a range of the Rayleigh number from 10 4to 10 5, the inclination angle of coil xeuler from 0° to 90°, magnetic force parameter γ from 0 to 200 and Danumber from 5×10 -4to 5×10 -3. The results show that the overall heat transfer is enhanced gradually with the increase of γ number,Ra number and Da number. The resulted convection is symmetrical in terms of the angle at xeuler=45 ° when the range of inclination angle is from 0 ° to 90 °.
