Fully developed, laminar magnetohydrodynamic (MHD) flows in curved channels have been studied for the following cases: First, the peroblem of a parallel-plate curved channel flow in the presence of a radial magnetic field is investigated analytically. The geometry of this problem does not induce a secondary flow, but the results obtained for different curvatue parameters provided some physical insights for the flow in channels with finite cross-section. Second, the effect of a transverse applied field on the flow in a curved pipe of circular cross-section is analyzed. When the Dean number is small and the Hartmann number is large, a perturbation solution for the secondary flow is obtained. For those cases when the Dean number is in the range 0 less than or equal to D less than or equal to 5000 and the Hartmann number is in the range 0 less than or equal to M less than or equal to 30, the full equations are solved using an up-wind finite difference method. Third, the flow in channel with rectangular cross-section are studied. The numerical procedure applied to the circular cross-section is performed in the rectangular coordinate system. The effect of the aspect ratio of the channel on the flow is also studied.
