“…In [24], the quench of a single-layer REBCO-based CORC ® cable wound by three tapes with non-uniform terminal contact resistance R t was investigated. A 3D multiphysics model was built, including three modules coupled with each other, a T-A formulation model, a heat transfer model and an equivalent circuit model.…”

In recent years, the T-A formulation has emerged as an efficient approach for modelling the electromagnetic behaviour of high-temperature superconductor (HTS) tapes in the form of coated conductors (CCs). HTS CCs are characterized by an extremely large width-to-thickness ratio of the superconducting layer, normally up to 1000~6000, which in general leads to a very large number of degrees of freedom. The T-A formulation considers the superconducting layer as infinitely thin. The magnetic vector potential A is used to calculate the magnetic field distribution in all simulated domains. The current vector potential T is used to calculate the current density in the superconducting layer, which is a material simulated with a highly nonlinear power-law resistivity. This article presents a review of the T-A formulation. First, the governing equations are described in detail for different cases (2D and 3D, cartesian and cylindrical coordinates). Then, the literature on the implementation of T-A formulation for simulating applications ranging from simple tape assemblies to high field magnets is reviewed. Advantages and disadvantages of this approach are also discussed.

The Conductor on Round Core (CORC) cable has attracted increasing attention due to its strong and high-efficient current carrying capacity. It is considered as one of ideal candidate cables for manufacturing nuclear fusion magnets. Under the circumstance, the transport current distribution of the coils wound by CORC cables has significant impacts on the operating performance of nuclear fusion magnets. Considering the difficulty in experimental tests, numerical model is an effective way to illustrate transport current distribution of the multi-layer CORC coil and provide further insights into its working performance. Therefore, in this work, A 3D finite element model based on the H formulation is proposed to simulate a single-turn and multi-layer CORC coil. The validity of the model has been verified by experimental results. Based on the proposed model, the transport current distribution of the multi-layer straight CORC cable and the multi-layer CORC coil is compared and discussed. In addition, the current density distribution on the superconducting tapes of the multi-layer CORC coil is also investigated. This work can provide an important reference for the design and practical application of multi-layer CORC coils.

“…The well-known H-formulation is currently applied in such models [30]- [34] and it is usually considered as reference to verify other formulations [24], [26]. Recently, taking advantage of the high ReBCO aspect ratio, the hybrid T − A formulation (firstly introduced in [35]), based on thin shell approximation of the conductive tape, is gaining interest in view of the saving in terms of computational time [24], [26], [29], [36]- [38]. While macroscopical quantities (i.e., magnetization and AC losses) can be properly calculated assuming an infinitely thin SC films, the local distribution of current density in AC cannot reliably computed inside the SC tape [34].…”

“…The method currently used to impose a transport current in the T − A formulation doesn't guarantee any self-consistent current distribution (or redistribution) among tapes. In [39] an equivalent circuit model, applied also in [38], is proposed to compute the current redistribution during a quench, depending on the equivalent resistance of each tape and on self and mutual inductance. The model is coupled with the T formulation: the resistance is evaluated in the T module and the electric network gives back the current distribution.…”

Future collider accelerators will rely on high-temperature superconductors reaching high field up to 20 T and above. Among the existing high-temperature superconducting materials, the Rare-earth Barium Copper Oxide (ReBCO ) tapes arranged according to the Conductor-on-Round-Core (CORC ® ) concept could be a viable solution to wound accelerator magnets such as Cosine Canted Theta (CCT) magnets. Dedicated experimental characterization of the critical current to quantify the degradation due to the winding process and operating conditions should proceed in parallel to the development of numerical models capable to reproduce and, in perspective, predict the cable performance. This paper presents the development of a new multi-physics model for a CORC ® wound with ReBCO tapes together with its validation. The T − A formulation has been used leveraging the high aspect ratio of tapes, suitably coupled with a conduction thermal model which for the first time properly accounts for the cable convective cooling. The model developed in this work can accurately simulate the thermal, electric and magnetic behaviors and the current sharing among tapes by using a set of self-consistent boundary conditions adopted for the first time in this kind of simulations. The model is verified and benchmarked against other well-established formulations on a set of test cases. The comparison of the computed V − I characteristic of the straight cable to available experimental data shows that the main physics features of the cable are well captured by the model, including performance degradation due to cable tapering at the terminations.INDEX TERMS Numerical models, CORC ® cables, critical current, multiphysics model, high-temperature superconductors,hybrid formulation.
