Numerical Analysis of the Effect of an Inclined Coil on Thermomagnetic Convection of Air in a Porous Cubic Enclosure

Thermomagnetic convection of air in a porous cubicenclosure with an inclined electric coil is numerically investigated undermicrogravity environment. Biot-Savart's law was used to calculate magneticfield. The momentum equations and energy equations were solved by the DarcyModel and the local thermal non-equilibrium model. The results show that thenatural convection of air is strengthened in the porous cubic enclosure withthe increase of \gamma number and Da number. The resultedconvection is symmetrical in terms of the angle at x_\rmeuler=45^\circ when the range of inclination angleis from 0^\circ to 90^\circ. The coil inclination changes theNu_\rm m number and a local maximum is obtained at x_\rmeuler=45^\circ for every case. Localminima are obtained at x_\rm euler=0^\circ and 90^\circ.
