Enhancements of thermal performances of an active magnetic refrigeration device based on nanofluids

Abstract

In this work, an analytical study on the active magnetic regeneration cycle operating near room temperature using nanofluid as carrier fluid, in order to enhance the heat transfer in regenerator bed after magnetization and demagnetization process. For this purpose, a nanofluid based on Al2O3 has been proposed. A numerical simulation of 1D model based on the transient energy equations is used to describe the heat transfer between the magnetocaloric material and the carrier fluid in the regenerator bed. The obtained results are presented, discussed and com-pared with base fluid.
