Efficient Numerical Modelling of Field Diffusion in High-Temperature Superconducting Wires

摘要

Multidimensional field diffusion problems with front-type behaviour, moving boundaries and non-linear material properties are analysed by a finite volume front fixing method. Advantages and implementation challenges of the method are discussed with special attention given to conservation properties of the algorithm and achieving accurate solutions close to the moving boundaries. The technique is validated using analytical solutions of diffusion problems with cylindrical symmetry.
