Modelling and temperature regulation using a new material fenicr alloy in induction cooking device

Abstract EN

The interest of induction cooking is direct temperature obtained on pan without thermal inertia.

However to prevent overheating of the pan, it is necessary to obtain a well regulated temperature.

For this aim, we propose to use a new material, FeNiCr alloy, placed outside in the bottom of the pan.

In this paper, we model the magneto thermal phenomena of system by a finite element method (FEM) for the mean to determine the temperature evolution in the bottom of the pan taking into account the nonlinearity of system.

This study shows, that a temperature value exceed the desired value of cooking (200 - 300 ° C) ,when using a conventional pan (stainless steel).

In the aim to have a regulated temperature, a layer of new material, FeNiCr alloy, witch have a low Curie point (300 ° C), is placed in the bottom of the pan.

This technique assures a natural regulation of temperature.
