| Abstract | Abstract — AC losses are numerically evaluated for various types of multifilamentary tapes without twisting that actual Bi-2223 Ag-sheathed wires are idealized. The penetration process of magnetic flux into the superconductor filaments subject to Bean’s critical state model is simulated for the application of an external transverse magnetic field perpendicular to the broadest face of tape wire by means of energy minimization. The AC losses under cyclic fields are calculated from the distribution of a vector potential in an initial state. The influences of arrangements and shapes of the filaments on the losses are investigated as compared with those for a wire that the entire filamentary region is regarded as a homogeneous superconductor. Index Terms — AC loss, high-Tc superconductor, multifilamen-tary tape, perpendicular magnetic field. |
