| 摘 要： | 进行了热声发动机驱动阻容负载的实验研究;讨论了工作压力对热声驱动阻容负载性能的影响。随着平均工作压力的增大,负载入口处压力振幅和输出的声功率都明显增大,同时板叠热端温度有较大幅度下降,有利于低品位热源的利用和提高系统相对卡诺效率。

| Abstract: | Experiments of a thermoacoustic engine connected with a RC(Resistance and capacitance) load were carried out.The influence of working pressure on the performance of the thermoacoustically driven RC load was discussed in detail according to the experimental results.Pressure amplitude at load inlet and acoustic power output transferred to the load increase greatly with accretion of the working pressure,and at the same time the temperature of hot end of the stack decreases to a certain extent.It is beneficial to use possibly low-grade energy and to enhance the relative Carnot efficiency of the system. |
