Effects of the magnetic field magnitude and direction on the oscillatory thermogravitational convection regimes in a rectangular cavity

Computation results are presented for threshold oscillatory instability and oscillatory convection regimes for a liquid in a uniform horizontal or vertical magnetic field in a square cavity, whose vertical walls are at different temperatures. The results show that the convective flow intensity is weakly dependent on the magnetic field direction, however, strong magnetic fields influence the convective flow structure in other ways. The investigation also points to the oscillatory instability of the steady state solution.
