INVESTIGATION ON THE COMPRESSIBILITY OF GAS MEDIUM IN THE FIBROUS MATERIALS REGENERATOR

The principle and method to tune the traveling wave ratio of the acoustic field of the microminiature thermoacoustic-Stirling engine was given. The model of adjusting phase can tune the traveling wave ratio of the acoustic field basing on the tuning phase principle of the distributed driven membrane. Being compared with the experiment result, both the simulation and the experiment results coincided satisfactorily.
