Three-Dimensional Simulation of Qeshm Channel Currents

Qeshm Channel is a shallow and narrow waterway located between Qeshm Island and the mainland in the vicinity of Hormuzgan Province, Islamic Republic of Iran. This channel is important because of its economic, industrial, fisheries and navigation role it plays as well as environmental issues it presents in the region. A prognostic study was performed to simulate currents in this channel, using C...

Calculation of three-dimensional electromagnetic fields involving laminar eddy currents

The formulation of a method to solve steady-state electromagnetic field problems involving laminar eddy currents is described. Iron nonlinearity is included. The formulation is implemented using finite elements and the problems associated with the solution of the resulting nonlinear equations discussed. Experiments with a Newton-Raphson iteration and modifications to it are described and a best...

Three-Dimensional Eddy Current Analysis

A boundary element method has been developed for the analysis of 3D eddy current problems. This method is based on the boundary integral equation formulation with equivalent electric and magnetic currents and electric charge as unknowns. Linear shape functions, defined parametrically over a quadrilateral element, have been selected for the Galerkin’s method.

Three-dimensional calculations of the magnetic fields in a finite superconducting hollow cylinder in an applied axial magnetic field

In this study, a set of self-consistent coupled-integral equations for the local magnetic flux and current distributions in a finite superconducting hollow cylinder under an axial magnetic field has been directly derived by using the Biot-Savart law within the framework of the critical-state model. The equations were first solved numerically in the three-dimensional space before obtaining the h...
