- 論文の詳細を見る
A phase adjuster (PA) is proposed to improve the cooling effect of a loop-tube-type thermoacoustic cooling system. A PA is a device for accelerating the particle velocity. The PA is embedded in the loop tube and narrows the cross-sectional area of the part of the loop tube. The PA creates a strong boundary condition in which the particle velocity is accelerated. It is confirmed that the phases of the sound pressure and particle velocity are adjusted so that the sound generated in the loop tube is resonated with the total tube length at one-wavelength resonance. This results in a great improvement in the cooling effect of the thermoacoustic cooling system.
