Determination of Thermohydraulic Characteristics of Reciprocating Room Temperature Active Magnetic Regenerator| Chapter 1 | Research Trends and Challenges in Physical Science Vol.8

 

 A thermohydraulic characterization of a reciprocating room temperature active magnetic regenerator was numerically carried out in this chapter, using gadolinium particles as a magnetocaloric material and water as a heat transfer fluid. For varying water inlet velocities of 0.06, 0.08, 0.1, and 0.12 m.s -1, a two-dimensional transient flow model was developed using COMSOL Multiphysics software to determine the water flow distribution in two active magnetic regenerators with cross and parallel gadolinium particle distributions. The gadolinium particles have a radius of 1.5 mm and a separation of 0.9 mm between them. Using the same software, a second two-dimensional transient coupled flow and heat transfer model was developed to characterise the convective heat transfer in the active magnetic regenerator of cross gadolinium particles distribution for the same water inlet velocities based on the simulation results of this model.
