ShareTHERMODYNAMIC ANALYSIS OF MAGNETICALLY ACTIVE REGENERATOR FROM 30 TO 70 K WITH A BRAYTON-LIKE CYCLE.
Author(s) : MATSUMOTO K., HASHIMOTO T.
Type of article: Article
Summary
A MODEL ACTIVE REGENERATOR WITH A BRAYTON-LIKE OPERATION CYCLE WAS ANALYSED BY NUMERICAL CYCLE SIMULATION. DYSPROSIUM-ALUMINIUM SINTERED COMPOUND WHICH HAS A CURIE TEMPERATURE OF 50 K WAS ADOPTED AS THE MAGNETIC REGENERATOR MATRIX IN THE TEMPERATURE RANGE BELOW 70 K. FROM THE ANALYSIS, THE MODEL ACTIVE REGENERATOR WAS SHOWN TO HAVE THE POTENTIAL OF ATTAINING A LOWEST TEMPERATURE OF 30 FROM 70 K. THE OPTIMUM OPERATING CONDITIONS GIVING MAXIMUM REFRIGERATION CAPACITY ARE DISCUSSED AND THERMAL EFFICIENCY IS ESTIMATED.
