Résumé

Measurements of thermoacoustic prime movers with stacks made of copper wire mesh are presented. The resonance frequencies are below 100 hertz, which are useful to drive pulse tube refrigerators. Onset temperature and resonance frequency were studied. The influence of gas properties, frequency, mean pressure, mesh size and stack length on the overall performance were measured and expressed in terms of normalized input power, heater temperature and pressure amplitude.
