Abstract(in English) | In order to clarify the driving principle of the two-phase fluid thermoacoustic engine, theoretical consideration was given to the energy generation in the wet regenerator. First, using Raspet's theory, a theoretical formula representing the generated energy in the wet regenerator was derived. Next, the effectiveness of the derived theoretical formula was confirmed by experiments. Furthermore, based on the derivation formula, the generated energy distribution in the wet regenerator and the energy generation ratio of air and water were derived using the measurement results of the temperature distribution inside the regenerator. As a result, (1) energy generation based on water phase change is prominent near the high temperature end of the regenerator, and (2) energy generation due to water phase change accounts for about 60% of the total generated energy of the two-phase fluid thermoacoustic engine. In order to realize low-temperature driving of a two-phase fluid thermoacoustic engine, it was found that system design that fully considers these factors is important. |
