Numerical Simulation of Magnetic Fields in YBCO High Temperature Superconducting Flywheel Model

Calculations of the fields in YBCO superconductors do not fit easily into standard finite element methods designed for ferromagnetic materials. A new calculation procedure, which can be called the Trapped Field Magnet (TFM) method, is proposed in this paper to predict the magnetic flux distributions...

Summary:Calculations of the fields in YBCO superconductors do not fit easily into standard finite element methods designed for ferromagnetic materials. A new calculation procedure, which can be called the Trapped Field Magnet (TFM) method, is proposed in this paper to predict the magnetic flux distributions and the stiffness of a flywheel model. The experimental results in field-cooled condition showed that the proposed procedure could be used to calculate the magnetic flux distribution of hard superconductors
