摘要: This paper presents results from numerical modelling of non-twisted multifilamentary Bi-2223/Ag conductors with various geometry and filament arrangement. New anisotropic models Jc(B) n(B) have been employed in finite element method simulations under different operating conditions – applied AC transport current, external parallel perpendicular magnetic field, combined current field varying orientation. losses, as well flux densities square round wires arrangement calculated compared to those a 7-filamentary tape. The notion effective Ic(B) applications is introduced discussed. It demonstrated that the shape factor orientation local respect individual filaments are primary importance for loss magnitude applications. Outlined advantages using specific configuration given application.
