Numerical analysis of a linear reciprocating active magnetic regenerator.
Author(s) : NIELSEN K. K., BARBOSA J. R. Jr, TREVIZOLI P. V.
Summary
The active magnetic regenerative (AMR) refrigeration device developed at the POLO Research Laboratories, Federal University of Santa Catarina, Brazil, presented elsewhere in these proceedings is analyzed using two different numerical models; one for the AMR process and another for analyzing the demagnetizing field present in the regenerator. The results show agreement with the experimental trends presented elsewhere in these proceedings, however, the AMR model predicts a significantly larger zero-load temperature span than experimentally observed. The demagnetization model predicts little impact of the demagnetizing field on the internal field of the magnetocaloric regenerator bed.
