Buoyant Convection Heat Transfer of the Liquid LiPb Flow with a Transverse Magnetic Field
The nature convection of the liquid LiPb, due to thermal diffusion, in the poloidal channel adjacent to the First Wall (FW) perpendicular to the strong magnetic field of the blanket has been considered and studied. The cubic enclosure filled by the liquid metal LiPb flow is assumed as the analyzed model. It was numerical simulated by three-dimensional CFD with special MHD code. The Hartmann number is from 20 to 200. The wall of the enclosure was heated by a uniform temperature and the other wall was cooled along two opposite vertical walls, all other walls being adiabatic. The momentum equation and electrical-magnetic equations for the liquid LiPb flow in the enclosure have given. It is assumed the nature convection be steady-state conditions. The velocity and temperature of the LiPb flow with differential Hartmann number is discussed. The temperature distribution is changed due to magnetic field.There is a strong thermal coupling, modifying importantly the magnitude of the flow. The effect of the buoyancy on pressure driven duct flows has been investigated.
