Publication Annual Summary of Basic Research in Thermoacoustic Heat Transport: 1990(Monterey, California. Naval Postgraduate School, 1990-10) Atchley, Anthony Amstrong; Hofler, Thomas James; Physics (PH); Graduate School of Operational and Information Sciences (GSOIS); PhysicsPublication Annual summary of basic research thermoacoustic heat transport: 1992(Monterey, California. Naval Postgraduate School, 1992-11) Atchley, Anthony Amstrong; Physics (PH); Graduate School of Operational and Information Sciences (GSOIS); PhysicsThis 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.Publication Annual Summary of Basic Research in Thermoacoustic Heat Transport: 1991(Monterey, California. Naval Postgraduate School, 1991-10) Atchley, Anthony Amstrong; Physics (PH); Graduate School of Operational and Information Sciences (GSOIS); PhysicsThis annual report details progress in basic research in thermoacoustic heat transport made during the report period. Five projects are discussed: an experimental study of edge effects in thermoacoustic couple measurements, the application of porous media techniques to thermoacoustic prime mover, development of a non-boundary layer, non-short stack model for the power output of the thermoacoustic prime mover, the study of the transition to steady state oscillation in a thermoacoustic prime mover above onset of self- oscillation, and the study of energy distribution and dissipation in finite amplitude standing waves.
