Numerical analysis of an active magnetic regenerator

A one-dimensional transient model of an active magnetic regenerator has been developed. The magnetocaloric properties are calculated using the Mean field theory and the model is used to study the transient and steady state response of a parallel plate regenerator. A parametric study is performed and highlights the influence of the Number of Transfer Units, the Utilization, and the solid axial conductivity. Finally the magnetic field inhomogeneity and the fluid axial conductivity are found to have no significant influence on the regenerator performance.

► We present a comprehensive numerical analysis of an active magnetic regenerator.
► We perform a parameter study on both the temperature span and the cooling power.
► It highlights the influence of the Number of Transfer Units and the Utilization.
► Solid axial conductivity is seen to strongly reduce the regenerator performance.
► It is shown that the magnetic field inhomogeneity has no significant influence.
