Thermomagnetic convection with distributed source in coaxial gap

The plane convective motion of a viscous incompressible fluid in the gap between two long coaxial cylinders is analyzed numerically. It is assumed that the fluid is nonmagnetizable and electrically nonconducting, and that heat release is present. The influence of the intensity of the heat source on the structure of the flow and the nature of heat- and mass-transfer is studied. Asymptotic relations between the integral heat-transfer parameters and the magnetic Rayleigh number are obtained.
