Abstract: Numerical computations were carried out for thermal convection of air in a cubic enclosure under both magnetising and gravitational fields. A one-turned circular coil with electric current, which induces a magnetic field, was placed around the enclosure and inclined with its plane oblique to the hot and cold walls and with its centre at the centre of enclosure. Computations were carried out for several combinations of parameters: Pr = 0.71; Ra = 1.51 × 104, 9.06 × 104; γ = 10, 30, 60, 100; γeuler from - π/2 to π/2.

Keywords: numerical analysis; magnetising convection; gravitational convection; cubic enclosure; inclined electric coil; air convection; air flow; magnetic field; thermal convection; heat transfer.
