Piezoelectric Source Exciting Thermoacoustic Resonator: Analytical Modelling and Experiment
Nowadays, there exists an interest for designing thermoacoustic refrigerator involving smaller dimensions than classical ones. This implies to design piezoelectric acoustic sources devoted to the thermoacoustic applications and then to investigate the behaviour of the coupling between
piezoelectric loudspeaker and small thermoacoustic resonator, in order to provide the maximum acoustic energy transfer available in the resonator for the refrigeration process. The present work aims at contributing to investigate methods to describe the behaviour of this coupling, giving an
accurate model which takes the form of an equivalent electric network. Simple experimental results permit to validate the theoretical results obtained from the model.
