摘要
从热声热机的驻波热声效应机理出发,系统地研究了其中的声压和声速的相位关系式,指出实际的热声热机系统声场为驻波和行波混合声场,要提高循环效率,必须采用不同的循环气体和热声叠来适当地控制其中的驻波比。
It is given the phase relational expression between the sound pressure and velocity of sound based on the standing wave principle of the thermoacoustic effect in the Thermoacoustic - engine. The conclusion is that the acoustic field is mixed the standing wave with traveling wave in the Thermoacousticengine. In order to improve the efficiency, it is control the ratio of the traveling wave in the mix sound field by using the difference the working gas and the stack.
