Thermal modeling and analysis of a quasi-poloidal stellarator modular coil

A computer model of the Racetrack coil of a quasi-poloidal stellarator is used to investigate thermal transient behavior when pulsed with high-ampere currents to generate magnetic field. The analysis was carried out to determine hotspots and collect temperature data in the process. The rate of cooling under natural convective boundary conditions is determined. Also fluid cooling using liquid nitrogen is investigated. The optimal design location of the cooling lines in the Racetrack is confirmed. Experiments have also been carried out to determine the property data for the copper-glass-epoxy composite conductor coil, which is used in the computational analysis.
