Investigation of an Argon-Filled Thermoacoustic Prime Mover

Abstract

The goal of this thesis is to investigate the behavior of a thermoacoustic prime mover filled with argon. Data was collected for three different operating conditions: (1) prior to the onset of acoustic oscillation, (2) immediately after onset and (3) after the prime mover had reached steady state, at mean gas pressures of approximately 80 kPa, 205 kPa and 305 kPa. Measured values of 1/Q are compared to predictions of a theory based on Swift's work. After onset, Q is determined from measurement of the rise time of the oscillations. The data set collected is the first to span onset and results show good agreement with theory. It is concluded that the theory can be used to provide reasonable input for a model to predict the steady state waveforms.
