| 摘 要： | 进行了热声发动机驱动阻容负载的实验研究,分析讨论了阻容负载中声阻和容抗对整机性能的影响.首次通过实验验证了当声阻与容抗相等时,热声发动机向阻容负载传递的声功率最大.以氦气为工质,在充气压力2.1 MPa、加热功率2 000W的条件下,采用110 cm3的气库,在1台驻波型热声发动机上获得了最大43.1 W的声功率输出.

| Abstract: | Experiments of a thermoacoustic engine connected with RC(resistance and capacitance) load were carried out.The influence of the acoustic resistance and acoustic capacitance impedance on the whole thermoacoustic system was discussed.It was experimentally proved for the first time that the maximum acoustic power output can be transferred to the load when the acoustic resistance of RC load equals to its acoustic capacitance impedance.A maximum acoustic power 43.1 W output to RC load of 110 cm~3 capacitance was measured with helium filling of 2.1 MPa and heating power of 2 000 W. |
