Molten Metal Transport along the Surface under the Effect of Plasma Flows Typical of Transient Processes in Tokamaks

The metal surface erosion under powerful plasma pulse flows typical of transient processes in tokamaks, ELMs, and plasma disruptions and simulated on a quasistationary plasma accelerator (QSPA) is studied. The hillock relief formation on the molten metal surface over which the plasma flow parallel to the surface moves and also the formation of metal jets moving in the direction of the plasma flow are considered. On the basis of the motion of the jets, the molten metal transport along the surface and the erosion of this surface are explained.
