Multi-Field Coupling Simulation on Quench Process in Superconducting Magnet

Quench protection system is a necessary part in superconducting magnets design. Rational design of quench protection system requires understanding of heat transfer and electromagnetic process in the magnet during quench process. A multi-field coupling model was developed to study quench process. This model sequentially solves two different physics environments, one is thermal physics environment, and the other one is electromagnetic physics environment. This model was applied to simulate one solenoid magnet in practical engineering. The main parameters results during quench process were presented. This research enriches the theory of numerical simulation on quench process of superconducting magnet, and provides theoretical guidance for the design of quench protection system.
