Thermal analysis of superconducting traction transformer

Abstract

The paper deals with thermal analysis of the superconducting single-phase high temperature superconductivity (HTS) traction transformer. The purpose is to investigate a thermal distribution of a heat in a cryogen with liquid nitrogen using a FEM software and program Fluent. The outputs are time varying waveforms of temperature in certain points of the transformer, if the convection is neglected (it will be simulated by means of a 3D version of FEM software) and if the convection is taken into account by means of Fluent program.
