Development of magnetic vector potential formulations by one way-coupling suproblem technique-Application to electromagnetic thin shell problems

Abstract

Electromagnetic problems always exist and plays an important role in the fields of electrical systems in general and electrical equipments in particular. It can be considered as a spine problem decided to the working process of the electrical systems and devices.  Hence, the analysis, computation and simulation of physic phenomena, electromagnetic processes of the electromagnetic problems are really an important topic concerning for researchers in Viet Nam and in the world as well. In this study, a magnetic vector potential formulation is developed by one way-coupling subproblem technique  to calculate field quantities (magnetic field density, eddy current density, joule power loss) existing and occuring in thin conducting regions of electrical equipments (shieldings, iron cores, transformer tanks). The development of the method will be verified via the practical problem “TEAM problem 21, model B).
