title: Investigation on the different types of resonators in the thermoacoustic Stirling prime mover.
abstract: A new thermoacoustic Stirling prime mover consisting of a looped tube and different types of resonators respectively has been built. Experiments were focused on three axisymmetric types of resonators: cylinder, cone and cylinder-cone under the same operation conditions. Pressure ratios in the prime mover were observed, 1.15 for cylinder-cone, 1.092 for cylinder and 1.097 for cone. The acoustic fields along the looped tube and different types of resonators were calculated, which agreed well with the measured results.
