Local iRBF-DQ method for MHD duct flows at high hartmann numbers

Magnetohydrodynamics (MHD) is the study of the interaction between moving, conducting fluids and magnetic fields. In this paper, the discussion is restricted to incompressible, viscous and electrically conducting fluids through pipes and ducts under an imposed uniform, oblique magnetic field. The MHD issues have become increasingly important because of the practical engineering applications such as the design of cooling systems with liquid metals for a thermal nuclear fusion blanket. Blankets which rely only on the heat transverse ability of liquid metal are known as self-cooled liquid metal blankets. There are a number of amount of data and papers concerning the physical phenomena of liquid metal flows in the absence of a magnetic field. However, in a fusion reactor environment such as the first wall and the blankets, a strong magnetic field (high Hartmann numbers 3 5 10 M 10 ≤ ≤ ) by Molokov S & Buhler L 1,2
