音響共鳴管における熱輸送現象とその可視化

抄録

The resonance tube refrigerator developed by Wheatley et al. has given rise to great interest in the field of refrigeration technology. Fundamental investigation has been conducted on the resonance tube refrigerator using a simplified model. The temperature response of the stack in the tube has been visualized by using a thermosensitive liquid-crystal sheet. The visualized image has demonstrated the heat-transfer mechanism based on the thermoacoustic theory. The temperature distribution in the tube has been discussed with reference to the resonance tube configuration, the mode of resonance and the working fluid property.
