| Abstract(in English) | In this report we focus on phase difference between sound pressure and particle velocity in resonance tube to improve thermoacoustic cooling performance of a loop-tube. Thermoacoustic cooling performance is affected position of stack in resonance tube. Heat exchange between stack wall and working fluid is important for thermoacoustic cooling performance. We have to make consideration heat exchange areas both near the stack wall and near thermal boundary layer thickness changing heat exchange mode. It is confirmed that stack is placed behind the position which phase difference between sound pressure and particle velocity is 0 degree. As a result we improve thermoacoustic cooling performance. |
