摘要
将一种较为实用的两传感器的声功测量方法 ,应用于热声制冷机声功的测量中 ,分析和研究了制冷机声压和声功率随频率的变化特性 ,使用网络模型计算的结果与实验结果能较好地吻合 ,本研究也是对作者所开发的热声热机网络模拟计算程序和两传感器声功测量方法的验证与应用。
The application of two sensor method to the measurement of acoustic power of themoacoustic refeigerator is presented in this paper.The frequency characteristics of acoustic pressure and acoustic power of thermoacoustic refrigerator discussed here are investigated and analyzed.The results calculated with network model are in good agreement with that of experiments.These studied results in this paper also have provided verifications for the network program developed by authors for thermoacousitc heat engines and refrigerators,and for the method of two sensor to measure acoustic power of present thermoacoustic refrigerator.
