Computation of general nonstationary 2D eddy currents in linear moving arrangements using integrodifferential approach

Abstract

Purpose

Most eddy current problems are solved using numerical schemes based on the differential approach. Nevertheless, there exist several classes of tasks where use of this approach may be complicated (problems characterized by geometrical incommensurability of individual subdomains, motion, etc.). In such cases, application of the integrodifferential approach may be an advantage. The paper seeks to present the theoretical background of the method.

Design/methodology/approach

The mathematical model consists of a system of integrodifferential equations for current densities in electrically conductive domains.

Findings

The methodology is illustrated on an example. All computations are realized by a code developed and written by the authors.

Originality/value

The presented algorithm based on the integrodifferential approach makes it possible to solve problems that are only hardly solvable by classical differential methods.
