Study of heat transfers in a magnetocaloric regenerator with oscillating heat flow.

This paper propounds a modeling approach of the heat transfer in a magnetocaloric regenerator and the experimental method to evaluate correlations of the heat transfer coefficient between the magnetocaloric material and the coolant with an oscillating flow. This model includes a specific resolution for the fluid flow equations which takes into account a specific case of oscillating flows, the annular effect. These correlations can be used in the numerical model of a magnetocaloric heat pump to estimate the efficiency of this pump. This study involves the demonstrator development which allows to improve the numerical model.
