Description
The simulation of quench dynamics in superconducting magnets is crucial for understanding their thermal and electromagnetic behavior under fault conditions. From a numerical simulation point of view, this is a challenging multiphysics problem involving thermal, electrical and magnetic phenomena. This article presents an advanced application based on ANSYS APDL program developed to simulate the quench behavior of superconducting magnets, able to accommodate several geometries, including cos-theta, canted cos-theta, and solenoid configurations, providing a versatile tool for various applications.
While temperature-dependent material properties are commonly modelled in ANSYS, our simulation framework allows for the consideration of magnetic field-dependent material properties in the cable, such as magnetoresistivity and the superconducting critical temperature during the transient.
A key feature of the program is its ability to account for eddy current effects arising from AC transient phases (e.g. the current charge and discharge), allowing the simulation of quench-back phenomena in metal-insulated magnets and large detector magnets. Comparison between our tool and analytical evaluation will be made, exploiting the capability of our suite to support both adiabatic conditions and helium cooling.
