Abstract
This paper presents results from numerical modelling of BSCCO conductors performed with finite element method software. The AC losses are calculated and compared for conductors of different geometry and aspect ratio––an elliptical tape with anisotropic J c( B) and a round wire with isotropic J c( B), in external magnetic field of various angles. The difference in the losses of the wire and the tape is found to be significant and depends on the applied field's magnitude and orientation. Also studied is the effect of the lateral J c distribution along the width of a 37-filamentary tape. The AC losses in each filament are calculated and compared. Simulations with transport current only, as well as with applied AC perpendicular or parallel fields have been made for a model with constant J c and models with increasing and decreasing J c towards the edges of the tape.
