Abstract
A time-dependent one-dimensional model of the Active Magnetic Regenerator (AMR) is described. The model assumes that the heat capacity of the pore fluid in the regenerator is negligible compared to the magnetic material. Measured magnetic material properties are used, including the effect of hysteresis. The variation of the fluid helium properties with temperature are included. Heat transfer between the fluid and bed is obtained from an emperical correlation, as is the pressure drop, axial conduction and axial dispersion.
Equations are presented and the numerical procedure used to solve them is discussed with emphasis on accuracy. The model has been applied to results from an AMR test device.
