This annual report details progress in basic research in thermoacoustic heat transport irade during the period October 1, 1991 through September 30, 1992. Our major research efforts were concentrated in two ateas during FY1992: 1) a standing wave analysis of the low amplitude performance of thermoacoustic prime movers both below and above the onset of self-oscillation and 2) a study of finite amplitude standing waves in both harmonic and anharmonic tubes. In addition to these areas, FY1992 research efforts also included the investigation of heat driven refrigerators and preliminary work on investigations of thermoacoustic engines with laser Doppler anemometry. This technical report summarizes the important results of these projects. A publications, patents, presentations, and honors report is also included.
