【摘要】 利用沿轴向均匀布置在回热器内部的4个温度传感器,采集了不同工况条件下的回热器内部温度,并在现有的渗透深度等回热器参数模型和实验获得的系统谐振频率的基础上,计算了回热器的相关参数,进而分析了这些参数的变化规律,验证了热声系统谐振模态的动态演化过程。更多还原

【Abstract】 In the thermoacoustic system four thermoelectric couples were even distributed a long the axis of regenerator to record interior temperature of the regenera tor in different regimes, and the oscillatory frequency of the system was measur ed through experiment. Then the parameters of regenerator were calculated and th e transforming rules of the parameters were analyzed.The dynamic character of os cillatory mode of thermoacoustic engine was validated.更多还原
