A one-dimensional model of a parallel-plate active magnetic regenerator (AMR) is presented in this work. The model is based on an efficient numerical scheme which has been developed after analysing the heat transfer mechanisms in the regenerator bed. The new finite difference scheme optimally combines explicit and implicit techniques in order to solve the one-dimensional conjugate heat transfer problem in an accurate and fast manner while ensuring energy conservation. The present model has been thoroughly validated
against passive regenerator cases with an analytical solution. Compared to the fully implicit
scheme, the proposed scheme achieves more accurate results, prevents numerical
errors and requires less computational effort. In AMR simulations the new scheme can
reduce the computational time by 89%.
