Low computational cost semi-analytical magnetostatic model for magnetocaloric refrigeration systems

The analysis of the active magnetic refrigeration (AMR) cycle for different waveforms of both the magnetic field and the velocity of the heat transfer fluid is an essential challenge in designing and implementing heating and cooling systems based on the magnetocaloric effect. One of the most importa...
