Deformation Induced by Magnetic Field on GaInSn Flow Surface
Liquid metal divertors are expected to have higher thermal load tolerance compared with solid divertors. Precise prediction of liquid metal behavior using magnetohydrodynamic (MHD) simulation enables the practical designing of a liquid metal divertor. The aim of this study is to confirm the accuracy of an MHD simulation that is developed for liquid metal flow prediction. As a benchmark test of the MHD simulation, a comparison of the Galinstan flowing through a vertical magnetic field and the simulated results was performed, and qualitative reproduction using the MHD simulation was confirmed. In addition, the source of wave creation and the causes of failure of the quantitative reproduction were investigated, which is may caused by the variations of the Galinstan surface tension.
