Numerical examination of liquid metal magnetohydrodynamic flow in multiple channels in the plane perpendicular to the magnetic field

다국어 초록 (Multilingual Abstract)

In the current study, investigated are steady-state, three-dimensional liquid metal (LM) magnetohydrodynamic (MHD) flows in a conduitsystem including three sub-channels with co-current flows under a uniform magnetic field. Though there have been numerous analytic,experimental and numerical studies on MHD duct flow, detailed flow characteristics of a LMMHD flow in a conduit system withmultiple channels have not been reported much. The current study predicts detailed behaviors of the flow velocity, pressure, current andelectric potential of LMMHD flows in multiple channels in the plane perpendicular to the magnetic field. Here, the characteristics of theMHD flow in a conduit system with multiple channels are elucidated. The mass flow rate in each of outer channel turns out to be higherthan that in the central channel. The mechanism governing the imbalance of mass flow rate in the sub-channels is discussed in detailbased on the interdependency of flow variables in LMMHD flow.
