Thermoacoustics is a promising field that uses the phenomena of acoustic wave interaction with neighboring solid boundaries to build engines for power generation. A typical thermoacoustic heat engine (THE) converts heat from an input source to acoustic energy, which is then collected by an alternator to generate electricity. Moving parts are present in an alternator, rendering it expensive and less reliable. A viable alternative is the use of Triboelectric nanogenerators (TENG) as a conversion system. Thus, a thermoacoustic heat engine integrated with a TENG is modeled and analyzed in this paper. A three-tier methodology including analytical, FEM, and an electrical analogy approach is adopted to simulate and optimize the performance of a TENG-attached-THE. The simulation results show that a voltage and current of 11.2 V and 0.028μA, respectively, are produced, differing by + 1.2 V and + 0.013μA with the experimental results.

热声学是一个很有前途的领域，它利用声波与邻近固体边界的相互作用现象来构建发电引擎。典型的热声热机 (THE) 将来自输入源的热量转换为声能，然后由交流发电机收集以发电。交流发电机中存在活动部件，使其价格昂贵且可靠性较低。一个可行的替代方案是使用摩擦纳米发电机 (TENG) 作为转换系统。因此，本文对集成了 TENG 的热声热机进行了建模和分析。采用包括分析、FEM 和电气类比方法在内的三层方法来模拟和优化 TENG-attached-THE 的性能。仿真结果表明，电压和电流分别为 11.2 V 和 0.028μA，
