Numerical Simulation of Coupled Electromagnetic and Thermal Fields in Cable Terminations
TELSIKS 2005 - 2005 uth International Conference on Telecommunication in ModernSatellite, Cable and Broadcasting Services, 2005 This paper deals with the distribution of the conduction current in a high-voltage cable termination with an imperfect insulation or polluted insulation. The thermal effect of the conduction current in an imperfect insulation is included in the model. The case of the variable resistivity of the insulation is included in the analysis of the termination.

, 2012 The main goal is to present results of numerical simulations of induction heating process in pieces of cylindrical shape, using an inductor with variable step between the coils. Inducting heating process modelling was made with the Flux2D software and for study we present the temperature charts of the billet at different time steps.

IEE Half-Day Colloquium on Electromagnetics and Induction Heating, 1996 Induction heating has long been recognised as an efficient, clean rapid method of heating billets for forging, extrusion and other metal forming operations. A typical practical computer model is described, which continuously recalculates the transient temperature distribution throughout the heating cycle.

Coupled Electromagnetic-Thermal Field Investigation in Induction Heating Device
Solid State Phenomena, 2009 The aim of the work is precise coupled –electromagnetic and temperature field analysis of an induction heating system by finite element method. Presented example is referred to real induction heating system. The problem was solved as nonlinear, transient and axisymmetrical. The numerical model of the coupled fields is based on the finite element method

Solution of Coupled Electromagnetic and Thermal Fields
, 2019 The objective of this chapter is to discuss the electromagnetic and thermal simulation requirements when designing large power transformers; in particular, the focus will be on the study of overheat problems in the transformer tank due to the leakage flux and the induced eddy currents. There are a number of requirements for the model specification, the

A nonlinear electromagnetic-mechanical-thermal multi-field coupled model for Galfenol rods
2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019 A nonlinear electromagnetic-mechanical-thermal multi-field coupled model for Galfenol rods is established with the theory of Gibbs free energy, Jiles-Atherton model, Stoner-Wohlfarth model and the hybrid vector magnetic hysteresis model. The model considers the electromagnetic-mechanical-thermal coupling terms, dynamic losses properties and the ...

Digest of the Fifth Biennial IEEE Conference on Electromagnetic Field Computation, 2005 N-dimensional equation for the coupled physical field is proposed. It is unified representation for various physical field In N-dimensional space. When the analogy (dualty) physical quantities and analogy coefficients have been chosen, the equation of a given field and the numerical solution of FEM can be determined.
