An experimental study of passive regenerator geometries.

Author(s) : ENGELBRECHT K., NIELSEN K. K., PRYDS N.

Summary

To optimize the design of an active magnetic regenerative (AMR) system, it is crucial to understand both the regenerator design and magnetocaloric properties of the system. This paper investigates methods of improving the performance of flat-plate regenerators for use in AMR systems. In order to eliminate experimental uncertainty associated with magnetocaloric material properties, all regenerators are made of aluminum. The performance of corrugated, plates and dimpled plates are compared to traditional flat plate regenerators for a range of cycle times and utilizations. Each regenerator is built using 18 aluminium plates with a 0.4 mm thickness, which allows their performance to be compared directly.
