Magnetohydrodynamic experimental design and program for Chinese liquid metal LiPb experimental loop DRAGON-IV

To investigate the key issues of the liquid metal LiPb blankets, liquid metal LiPb experimental loop is necessary equipment, and the magnetohydrodynamic (MHD) experiment is one of the important parts for investigation of the LiPb flow characteristics under the magnetic field of the magnetic confinement fusion reactors. Considering the design features of the LiPb blanket and the engineering feasibility, the MHD experiment duct was developed for Chinese liquid metal LiPb experimental loop DRAGON-IV. In this paper, the design scheme and parameters for MHD experiment duct were given. The performance analyses about MHD flow characteristics and stress were presented. And future MHD experiment program was specified.
