Description

The high‐temperature superconducting (HTS) dynamo enables injection of large DC currents into a superconducting coil, without the need for thermally‐inefficient current leads. Because of this important advantage, there is significant interest in using such technology to energise superconducting coils in a range of applications including superconducting rotating machines and NMR/MRI magnets. Numerical modelling has played a key role in elucidating the underlying physics of such devices and several different numerical models have now been developed as useful and cost-effective tools to examine experimental results, as well as optimise and improve dynamo designs. This talk summarises recent developments in this important area, including modelling the open‐circuit voltage behaviour in 2D and 3D, the definition of a new benchmark problem for the HTS modelling community, investigating key dynamo parameters, modelling dynamic coil charging behaviour and calculating losses. Some comments on the future of such modelling is provided, including some outstanding challenges.
