| Outline of Final Research Achievements |
A thermoacoustic system is a system of heat and acoustic energy conversion. When there is a stack with a lot of narrow tubes in a standing wave field, difference of temperature occurs at the both ends of the tubes. A honeycomb ceramics, stainless mesh and glass tubes were used as the devices of the energy converter from sound to heat. Although thermoacoustic effect was confirmed for all the devices the temperature difference depended on each devices. Therefore stacks are molded using a 3D printer in this study. When the inner shape of the stack has a spiral shape, it is possible to build a longer narrow tubes in the same capacity. In addition, it can increase surface area to contribute to heat exchange. It produced several stack were with various angle of the spiral. Difference of temperature was experimentally measured between the both ends of the stack in the standing-wave type thermoacoustic cooler.
