TL;DR: In this article, the authors discuss some of the main challenges encountered in the literature and how design choices impact cooling power and work requirements from a system engineering perspective, and propose an extended design/optimization methodology based on entropy generation minimization with performance criteria.

TL;DR: In this article, a one dimensional, time dependent model is used to study the performance of an active magnetic regenerator in terms of cooling power and second law efficiency for a range of displaced fluid volumes and operating frequencies.

TL;DR: A permanent magnet topology optimization to minimize the total cost of cooling using a thermoeconomic cost-rate balance coupled with an AMR model is presented and a genetic algorithm identifies cost-minimizing magnet topologies.

TL;DR: In this paper, a flow control mechanism based on cam actuated valves is designed and implemented on an active magnetic regenerator test apparatus to overcome the brief low field period of the nested concentric Halbach array by decreasing the fluid blow width, displacing fluid only when the magnetic field was close to the minimum and maximum values.

TL;DR: In this article, four regenerator compositions comprised of two-layers are experimentally tested with interface temperature measurements, and the two-layer regenerators present the largest performance improvements for the no-load conditions and, in general, develop the peak exergetic cooling power for almost all operating conditions.
