Abstract
In thermoacoustic systems, stacks with different matrix geometry and material coupled with different acoustic systems present different heat dynamic performances, which have influences on the efficiency of energy conversion. Then the quality factor is used to evaluate the performance of each matrix and verified experimentally in thermoacoustic system. It is showed that the pin-array matrix has the best quality factor and the lowest dissipative performance compared with other matrix.
