Our research is about arbitrary geometry thermoacoustic engines. The specific geometry studied in detail is the radial wave arrangement. Formal theory and the short stack approximation were derived for this geometry and were used to pursue an answer to the following question Radial or plane wave thermoacoustic refrigerators To date, the plane wave refrigerator appears to be the best overall compromise refrigerator, though the radial wave refrigerator has a higher cooling capacity. An evolving numerical design program has been enhanced to include radial or plane wave engines with variable plate spacing and both plane and radial wave resonators simultaneously with application to driving radial wave refrigerators with heat driven plane wave sound sources. Our experiments have mainly been aimed at radial wave prime movers for the purposes of validating the theory and investigating the large amplitude behavior. Heat exchanger design is a critical issue.
