  • The heat transfer rules between the porous medium and single-phase fluid under the periodical instantaneous heat source in the active magnetic regenerator (AMR) of a rotary magnetic refrigerator were discussed based on temperature field measurement.The experimental results showed that the temperature vibration frequency in the AMR was equal to the rotational frequency of the AMR.With the increasing of the rotational frequency of the AMR,the temperature vibration frequency increased accordingly,but the temperature values decreased.On the other hand,the temperature vibration frequencies in demagnetizing area and magnetizing area were the same,the vibration phase shift between the two areas was about 180 degrees,and the vibration amplitude of the former area was nearly twice as lange as that of the latter one.Generally,increasing the rotational frequency of the AMR has a positive effect on the refrigeration capacity,but the temperature reached its climax as the fluid flow increased to 2.639×10-4 m3/s,so the heat transfer fluid flow should designed to be less than the critical value.
