Performance Enhancement of a Magnetic Refrigeration Device based on TiO2 used as Secondary Fluid

The present work deal to study, a numerical modeling on the magnetic refrigeration machine operating near room temperature using nanofluid as carrier fluid, in order to enhance the heat exchange in regenerator bed after magnetization and demagnetization process. For this purpose, a nanofluid based on TiO2has been proposed. A numerical simulation of a 1D model based on the transient energy equations is used to describe the heat exchange between the magnetocaloric material and the carrier fluid in the regenerator bed. The obtained results are presented, discussed and compared to base fluid.
