3D Multiphysics Modeling of Bulk High-Temperature Superconductors for Use As Trapped Field Magnets
The authors are currently investigating the use of bulk high temperature superconductors as trapped field magnets (TFMs) in order to increase the electrical and magnetic loading of an axial gap, trapped flux-type superconducting electric machine. In electric machines, the use of superconducting materials can lead to increases in efficiency, as well as power density, which results in reductions ...
متن کاملThe London field in bulk layered superconductors
In a composite superconductor in uniform rotation, the London field strength at equilibrium is given by the usual expression BL = 2mω/e; here m corresponds to the bare electron mass, although the effective mass m can be different in different layers. In the presence of strong angular accelerations, however, transient phases and differences in m can become relevant. In particular, if the layers ...
متن کاملPenguins use the two-voice system to recognize each other.
The sound-producing structure in birds is the syrinx, which is usually a two-part organ located at the junction of the bronchi. As each branch of the syrinx produces sound independently, many birds have two acoustic sources. Thirty years ago, we had anatomical, physiological and acoustical evidence of this two-voice phenomenon but no function was known. In songbirds, often these two voices with...
متن کاملQuasi-one-dimensional superconductors: from weak to strong magnetic field
We discuss the possible existence of a superconducting phase at high magnetic field in organic quasione-dimensional conductors. We consider in particular (i) the formation of a Larkin-OvchinnikovFulde-Ferrell state, (ii) the role of a temperature-induced dimensional crossover occuring when the transverse coherence length ξz(T ) becomes of the order of the lattice spacing, and (iii) the effect o...
متن کاملInfluence of temperature and / or field dependences of the E – J power law on trapped magnetic field in bulk YBaCuO
— Temperature, current density and magnetic field distributions in YBCO bulk superconductor during a pulsed-field magnetization (PFM) process are calculated using the finite difference method. Simulations are based on the heat diffusion equation with account of the heat produced by flux motion, and Maxwell's equations. A power law with temperature and magnetic field dependent parameters is used...
