Abstract This paper presents a study of the impact of the resonance tube on performance of a thermoacoustic stack. The resonance tube is a key
component of a standing-wave thermoacoustic refrigerator. The appropriated resonance tube’s length leads to an increase of performance of the
stack in terms of the temperature difference. The results also indicate that the optimal operating frequency differs from the design based on the
equation of a half-wavelength. The resonance tube length is elongated to compensate for some effects that occur in the resonance tube,
especially when the stack is placed in the resonance tube. The relationship of… More >
