Abstract(in English) | We suggest a silencer for using thermoacoustic phenomenon of energy conversion of heat energy and sound energy. Thermoacoustic silencer is new type silencer, because it attenuates sound energy for using heat energy. First, we measured basic property that thermal, frequency, and channel radius of stack. As a results, it was determinate that silencing effect was saturated by stack was applied over a temperature gradient. Multistage stack method was introduced to improve silence effect. So, we succeeded in increasing efficiency of energy conversion by separating heat energy into two parts. Finally, we investigated practicality of multistage stack method by measuring sound field under the condition of two stacks into resonance tube. |
