A Study of Element Interactions in Thermoacoustic Engines
Abstract
The general performance of a thermoacoustic prime mover or refrigerator is reasonably well understood. There are notable discrepancies between theory and experiment. These discrepancies are typically attributed to nonlinear terms not included in the theory. There is evidence, however, that interactions between elements in the thermoacoustic device are at least partially responsible. An experimental investigation of the element interactions in a thermoacoustic prime mover and comparison to theoretical predictions was undertaken in this dissertation to minimize the temperature difference across the stack necessary to achieve onset of self oscillations (Delta T). This was accomplished by varying the position or physical dimensions of the thermoacoustic system or elements to modify the interactions and modifying the working fluid properties through binary mixing.
