Abstract In this paper, we experimentally measure the temperature fields at different locations on the stack plate and in the surrounding working fluid in
a standing wave thermoacoustic device. The temperature measurements at the stack extremities and at the neighboring gas show axial heat
transfer at the stack extremities, as opposed to the hypothesis of a perfectly isolated stack used in the linear thermoacoustic theory. Four
different mechanisms of heat transfer are identified at the stack extremities in the present study. This information is necessary for the
optimization of the performances of practical thermoacoustic engines. For the selected operating conditions, temperature… More >
