A simplified one-dimensional model of thermoacoustic devices, obtained by integrating the governing equations over the tube cross section, was described earlier. Here the results of a numerical exploration of the model as applied to a prime mover are described. The effects of temperature distribution, wall drag, heat transfer, and cross-sectional area variations are explored and compared with available experimental results. Some initial results for the heat pump configuration will also be presented. [Work supported by the Office of Naval Research.]
