| Outline of Final Research Achievements |
The purpose of this study is experimental examination of the behavior of liquid metal jets by MHD(magnetohydrodynamics) effect when the electric current flows along the jet in the presence of an external magnetic field.
The experiment showed the following three facts. Liquid metal jets can be stabilized by inserting an internal flow resistance as shown in the prior experiment using a water jet. Liquid metal jets deformed with the internal flow resistance in the presence of the MHD effect. The deformation of the jet can be calculated by the Lorentz force that works on the jet when it is regarded as a single conductor.
These results give a design guideline for the divertor, the component of a fusion reactor that accommodates ultra high heat load in steady state to remove impurities from the core plasma, using a liquid metal jet.
