title = "Design study of anharmonic standing wave thermoacoustic heat engine",
abstract = "The study presented here aims to design and optimize anharmonic Thermoacoustic Heat Engine. The study features the use of non-conventional resonator shape. The modeling as well as the main procedures towards optimizing the device is presented. A reasonable comparison between the device described here and cylindrical standing wave thermoacoustic heat engine is consequently presented. This comparison was conducted to investigate the effects of the resonator geometry on the acoustic pressure. Additionally, the investigation was to determine the ability of acoustic pressure to impede flow through the resonator. A change in the resonant frequency was observed in the anharmonic resonator from that of the cylindrical one. On other hand, for anharmonic resonator, an increase in the acoustic pressure amplitude for the fundamental mode has been observed with reduction in the amplitudes for higher harmonics. The geometry of the stack and the heat exchangers have been adjusted according to the changes observed in the frequency and the amplitude of the fundamental mode. The overall performance of the anharmonic heat engine was compared to that of cylindrical heat engine. The device designed using this resonator is able to theoretically work at an efficiency of 27.6 \% of that of Carnot cycle.",
