## Description

- description: The packed sphere bed regenerator is often utilized in active magnetic
    regenerative refrigeration (AMRR) because of its high heat transfer coefficient.
    However, the complex flow between the spheres in this regenerator causes an undesirable
    high pressure drop. In this study, we propose to adopt the Gyroid structure as
    a regenerator, which has a more structural design flexibility and a smoother flow,
    resulting in a lower pressure drop. The basic characteristics of various Gyroid
    regenerators were investigated by numerical simulations taking into account of
    heat transfer coefficient, pressure drop, and thermal conductivity, for the purpose
    of applying such regenerator in the AMRR system. The result of AMRR simulation
    shows that the standard Gyroid regenerator reduces the pressure drop by 45% while
    maintaining the cooling performance. In addition, two modified Gyroid regenerators
    have succeeded in further reducing the pressure drop with small decrease in cooling
    performance. This study shows that the Gyroid regenerator can serve as a potential
    regenerator to improve the energy efficiency of the AMRR system.
