本文的目的是介绍热声环管发动机的设计和实验验证过程。设计过程包括使用DELTA EC工具对系统进行数值建模，低振幅热声能量转换的设计环境，特别是平均压力和回热器配置对压力振幅和声功率的影响。随后是一个实际的发动机系统的建设配备了陶瓷再生器-一个基板上使用的汽车催化转化器与精细的方形通道。给出了初步的测试结果，并与仿真结果进行了比较.测量结果在定性水平上非常一致，在定量意义上也相当接近。
The aim of this paper is to present the design and experimental validation process for a thermoacoustic looped-tube engine. The design procedure consists of numerical modelling of the system using DELTA EC tool, Design Environment for Low-amplitude ThermoAcoustic Energy Conversion, in particular the effects of mean pressure and regenerator configuration on the pressure amplitude and acoustic power generated. This is followed by the construction of a practical engine system equipped with a ceramic regenerator — a substrate used in automotive catalytic converters with fine square channels. The preliminary testing results are obtained and compared with the simulations in detail. The measurement results agree very well on the qualitative level and are reasonably close in the quantitative sense.
