Abstract

This paper focuses on the numerical and experimental investigation of the small-scale power generator. The travelling wave thermoacoustic power generator is numerically analyzed and experimentally tested. The cyclic analysis is used to carry out numerical analysis of the power generator. The system is operated on atmospheric pressure, which allows the manufacturing of an acoustic feedback loop using Polyvinyl chloride piping. The acoustic power generated inside the generator is harnessed by the low-cost linear alternator, i.e., loudspeaker. The effect of regenerator wire mesh on performance of the power generator is numerically analyzed and validated experimentally. The numerical analysis identifies the temperature variation, pressure fluctuation, volume flow rate inside the system, and acoustic power distribution. The maximum electric power experimentally generated by the small-scale power generator is around 45 W with overall efficiency 8.30%. The alternator generates the maximum electric power at the optimum location, i.e. 2.30 m away from the engine core.

利用循环分析评估环形管热声发电机的性能

本文重点对小型发电机进行了数值和实验研究。对行波热声发电机进行了数值分析和实验测试。循环分析用于对发电装置进行数值分析。系统在大气压力下运行，因此可以使用聚氯乙烯管道制造声反馈回路。发电机内部产生的声功率由低成本的线性交流发电机（即扬声器）利用。对再生器金属丝网对发电机性能的影响进行了数值分析和实验验证。数值分析确定了温度变化、压力波动、系统内部的体积流量和声功率分布。小型发电机实验产生的最大电力约为 45 W，总效率为 8.30%。交流发电机在最佳位置（距离发动机核心 2.30 米）产生最大电力。
