Abstract : The performance of a working prototype, operated with and without water flow through the heat exchangers, was measured and found
to be in reasonably close agreement to predictions from a simulation code, DELTAE, based on linear thermoacoustic theory. Further
analysis and DELTAE simulations showed that the coefficient of performance may be significantly reduced when the stack temperature
profile becomes non-linear, i.e. when the system is operated for a temperature span smaller than the optimal value for a given stack
length. Guidelines to avoid this condition are provided.
