N2 - This paper reports the acoustic power source for self-sustained oscillations in a typical thermoacoustic system through measurements of acoustic intensity. Results show that the stack region with a steep temperature gradient produces the acoustic power necessary to compensate for energy dissipation in the other regions of the system. Based on this observation, we propose a quality factor measurement for predicting experimentally the critical temperature ratio before the system reaches the onset of oscillation.
