Current patterns and loss contributions in CORT cables carrying AC current
Benoît Vanderheyden, Julien Dular, Louis Denis +4
Conductor-on-round-tube (CORT) cables are a potential solution for carrying AC power in a small cross-section. Due to the geometry of the cable and the helical arrangement of the c…
Extending Field Limits in Nanoscale Magnetic Imaging with Metamaterial-inspired Magnetic Flux Concentrators
A. Barrera, E. Fourneau, T. Pirottin +14
Many nanoscale magnetic imaging techniques are constrained by the maximum magnetic field that can be applied during measurements, due to geometrical limitations or interactions wit…
Explicit Turn Resolution with Anisotropic Homogenisation for Efficient 3D Magneto-Thermal Finite-Element Simulation of Large-Scale No-Insulation HTS Magnets
Louis Denis, Erik Schnaubelt, Julien Dular +3
No-insulation (NI) and metal-insulation (MI) high-temperature superconducting (HTS) magnets require three-dimensional (3D) models to describe the current distribution around critic…
Homogenization of HTS coils with the h, h-phi, and t-omega foil conductor model
Elias Paakkunainen, Louis Denis, Benoît Vanderheyden +3
Efficient numerical models are required for the design of systems with high temperature superconductor (HTS) coils, as fully resolved finite element simulations of individual coate…
Simultaneous Multi-Scale Homogeneous H-Phi Thin-Shell Model for Efficient Simulations of Stacked HTS Coils
Louis Denis, Benoît Vanderheyden, Christophe Geuzaine
The simulation of large-scale high-temperature superconducting (HTS) magnets is a computational challenge due to the multiple spatial scales involved, from the magnet to the detail…
Acceleration of Multi-Scale LTS Magnet Simulations with Neural Network Surrogate Models
Louis Denis, Julien Dular, Vincent Nuttens +3
While the prediction of AC losses during transients is critical for designing large-scale low-temperature superconducting (LTS) magnets, brute-force finite-element (FE) simulation…
Magnetic Field Conforming Formulations for Foil Windings
Louis Denis, Elias Paakkunainen, Paavo Rasilo +3
We extend the foil winding homogenization method to magnetic field conforming formulations. We first propose a full magnetic field foil winding formulation by analogy with magnetic…
AC Loss Computation in Large-Scale Low-Temperature Superconducting Magnets: Multi-Scale and Semi-Analytical Procedures
Louis Denis, Vincent Nuttens, Benoît Vanderheyden +1
In this paper, we introduce two complementary approaches for the accurate prediction of AC losses in large-scale low-temperature superconducting (LTS) magnets. These methods accoun…
Helicoidal Transformation Method for Finite Element Models of Twisted Superconductors
Julien Dular, François Henrotte, André Nicolet +3
This paper deals with the modelling of superconducting and resistive wires with a helicoidal symmetry, subjected to an external field and a transport current. Helicoidal structures…
Magneto-Thermal Thin Shell Approximation for 3D Finite Element Analysis of No-Insulation Coils
Erik Schnaubelt, Sina Atalay, Mariusz Wozniak +6
For finite element (FE) analysis of no-insulation (NI) high-temperature superconducting (HTS) pancake coils, the high aspect ratio of the turn-to-turn contact layer (T2TCL) leads t…
