Description
Liquid metal (LM) blanket concepts are designed by many countries due to its attractive features such as geometric adaptability, good thermal conductivity and heat carrying capacity, et al. However, they all have feasibility issues associated with magnetohydrodynamic (MHD) interactions under the environment of a strong control magnetic field and the flowing high electrical conductivity LM. The MHD effect is affecting flow distribution and stability as well as the coupled heat transfer have a profound impact on fusion reactor operation and safety. Numerical simulation is presented in this paper to investigate the influence of non-uniform magnetic field on laminar buoyant MHD flows in rectangular ducts. The code is validated by ALEX experiment data and magneto-convection phenomenon analytical solution. The MHD flowing under the different direction of magnetic field and gravity is investigated numerically. The difference of pressure distribution between heat transfer MHD flow and pure MHD flow is also compared.
Keywords: MHD flows; laminar buoyant; liquid metal; non-uniform magnetic field.
