摘要: Cold disruptive plasma tends to move during the current quench. Its motion is essentially force-free since quench timescale resistive rather than Alfvenic. In contrast hot vertical displacement events, frozen-in condition violated in cold case, and not governed by magnetic flux conservation but its dissipation. We present a numerical model of dynamics. This predicts electromagnetic loads on vacuum vessel, flow density evolution, centroid evolution. Our calculations include poloidal wall currents. demonstrate their significant contribution force acting vessel.Cold vessel.
