Main research activities or contributions related to the HTS Modelling Workgroup
Numerical modelling is one of the most important means to investigate the electromagnetic and thermal behaviours of superconductors. The objects of superconducting numerical modelling mainly include two categories, one is the simulation of tapes / stacks / cables for power transmission scenarios, the other is on bulk superconductors applied for trapped field magnets or pinning maglev. The modelling methods have many similarities between the two, but they have different challenges in specific implementation. The former faces challenges in mesh processing due to the ultra-thin coated conductor layers, while the latter has complex internal structural features due to the influence of the preparation process. In the latter, especially the maglev application, the magnetic field environment is complex and changeable, which brings difficulities to the numerical simulation of bulks.
I, together with my team, has long been committed to the application of HTS bulk in green maglev transportation, with real vehicle tests and numerical simulations are carried out in parallel.
