| Abstract: | Magnetohydrodynamic natural convection heat transfer in a rotating, differentially
heated enclosure is studied numerically in this article. The governing equations
are in velocity, pressure and temperature formulation and solved using the
staggered grid arrangement together with MAC method. The governing parameters
considered are the Hartmann number, 0≤$Ha$≤70, the inclination angle of the magnetic
field, 0$^◦$≤$θ$≤90$^◦$, the Taylor number, 8.9×10$^4$≤$Ta$≤1.1×10$^6$ and the centrifugal force
is smaller than the Coriolis force and the both forces were kept below the buoyancy
force. It is found that a sufficiently large Lorentz force neutralizes the effect of buoyancy,
inertial and Coriolis forces. Horizontal or vertical direction of the magnetic field
is the most effective in reducing the global heat transfer. |
