Coupled Thermal-Electromagnetic Model for Microwave Heating of Temperature-Dependent Dielectric Media

Microwave heating processes involve electromagnetic and thermal effects coupled together through the local temperature dependence of the material dielectric properties. This paper presents a one-dimensional model for the coupled electromagnetic-thermal process and demonstrates its solutions for typical problems. The local temperature dependence of the lossy dielectric medium is taken into accou...

Optimization of Fan Geometry for Urban Train Traction Motors using Coupled Numerical Electromagnetic and Thermal Analysis

One of the most important parameters in designing electrical motors is heat generation by the motor and the way it is dissipated. Temperature rising reduce efficiency and reliability of traction motors and leads to failure. In this paper, an urban train traction motor in a 3D computational fluid dynamics (CFD) simulation has been investigated. Maxwell software for electromagnetic simulation and...
