MHD formulations for the liquid metal flow in a curved pipe of circular cross section

“…The axial component of the electric current density is calculated by the Ohm's law from Eq. (17). Using this model, the computational cost is significantly reduced.…”

“…Then, the axial component of the electric current density J z is calculated by the Ohm's law from Eq. (17), where the transverse components of the electric current density are computed by the Ampere's law from Eq. (15).…”

“…This configuration could be a section of a bend or a turn of the fusion reactor blanket access ducts piping system [17,18]. The electromagnetic variables will be implemented with three different formulations.…”

Experimental Studies of MHD Pressure Drop of PbLi Flow in Rectangular Pipes Under Uniform Magnetic Field

“…The theoretical MHD pressure gradient in rectangular pipe under uniform magnetic field could be calculated by formula [29]:…”

Effect of fringing magnetic field on magnetohydrodynamic flow in rectangular duct

“…But the motion of liquid metal in fusion reactor strong magnetic field cause serious MHD effects, which have dramatic impacts on velocity distribution, heat transfer, pressure drop and the required pumping power for the cooling system. Therefore, the liquid metal MHD effect under fusion relevant condition is one of the key issues in making an optimal design for liquid metal blankets [11][12][13][14].…”
