Abstract : The purpose of this research project is to study the fundamental physical processes which are involved in production of high cooling powers from electrically driven thermoacoustic refrigeration. The results of these experimental investigations are then utilized to produce improved designs for the next generation of high power thermoacoustic refrigerators, chillers, and air conditioners. These research objectives are achieved by an integrated combination of experimental measurements on thermoacoustic components and subsystems, as well as complete refrigeration systems. Comparison of the measured performance to analytic models based on differential equations (low amplitude) and similitude (high amplitude) and to numerical models based on the Los Alamos National Laboratory Design Environment for Low-Amplitude ThermoAcoustic Engines (DELTA-E), are then made.
