| Abstract: | Measurements and analysis of the performance of a thermoacoustic engine driving a dissipative load are made.Onset temperature and resonance frequency are measured and studied.The factors are founded which cause the thermoacoustic prime mover to work on the second mode.The influence of mean pressure of gas,frequency and length of resonance tube on the overall performance are measured and analyzed.A maximum output of 31 W from the thermoacoustic prime mover is achieved.And a 25 degree temperature gradient is developed along the regenerator by use of the acoustic power. |

| Keywords: | thermoacoustic prime mover onset temperature resonance frequency acoustic power refrigerator |
