SM coupled with TT application: presentation and typical example

Presentation

The Steady State AC Magnetic coupled with Transient Thermal application allows the study of the evolution of electromagnetic and thermal phenomena during the induction heating process of a part.

General operation

This type of study is a coupling between two different applications, one for the evaluation of the electromagnetic field distribution, and the other computing the transient heating of the part as a result of induced power and of thermal transfer:

• the Steady State AC Magnetic application allows the computation of the power dissipated by Joule effect into the part to be heated (1)
• the Transient Thermal application (2) allows the study of the temperature evolution of the heated part

The power dissipated by Joule effect, computed by the magnetic problemapplication 1, is the source of the thermal problemapplication 2.

Important results

The important results obtainable with the Steady State AC Magnetic coupled with Transient Thermal application are those that can be obtained separately with each of the two coupled applications, i.e. with:

• the Steady State AC Magnetic application (see chapter Steady State AC Magnetic application: principles)

• the Transient Thermal application (see chapter Thermal applications: principles)

Typical example

A typical example of a problem treated as a Steady State AC Magnetic coupled with Transient Thermal application is depicted in the figure below.
