Finite element analysis of an eddy current heater for wind or water kinetic energy conversion into heat

Abstract

The paper presents 2D and 3D finite element

models for the analysis of the electromagnetic and

thermal fields and the local and global quantities in an

eddy current heater with permanent magnets, able to

convert the wind or water kinetic energy into heat.

Correlations between the input and output operational

parameters of the heater are studied taking into account

the temperature dependence of physical properties and

the magnetic nonlinearity.
