| Abstract: | Based on previous studies,the performance of a traveling-wave thermoacoustic engine with end coupling RC load was further studied.The inner diameter and length of the straight resonance tube were changed at the same time,so that the frequency was kept at 67.7 Hz to ensure the same acoustic power conversion characteristics inside the engine loop.The results indicate that when the inner diameter of resonance tube is 120 mm,the system has the best performance.A maximum output acoustic power of 512 W(using heli... |
