Description
With the rapid development of superconducting technology, the application scenarios for high-temperature superconducting (HTS) cables continue to expand, leading to increasingly complex configurations for cable installation. The thermal characterization of CORC cables is essential to ensure the stable and safe operation, making it an inevitable part of the design process of CORC cables. Due to the complex geometry of the CORC cables and the coupling of electromagnetic field, temperature field, flow field and others, the analysis of the thermal characteristics becomes extremely complex, especially under the complex laying configuration. Therefore, this paper proposes a feasible thermal analysis method for CORC cables in complex flow channels. First, according to the actual laying configuration of the HST cables, the complex flow channel was decomposed into a straight part and a curved part. Furthermore, a two-dimensional axisymmetric model for the straight part and a three-dimensional refinement model for the curved part of the superconducting cables were established based on COMSOL, and the thermal characteristics of the CORC cables in complex flow channels were analyzed. Finally, based on the above methods, the thermal characteristics of CORC cables under different pulsed currents were analyzed and the ability to withstand pulsed currents was determined.
