| 摘 要： | 为了方便获得热声系统较佳的回热器边界条件,提出了双声源法调制回热器边界声场的方案.基于Rott方程,推导出回热器以及有阻尼谐振管中的声场表达式,建立了回热器边界声场调制的理论模型,得到了回热器边界声场和双声源的声压之间的关系.理论分析表明双声源法可以实现回热器边界声场的任意调节,并实际讨论了各种回热器声场边界条件的调制方法.

| Abstract: | To achieve satisfied boundary conditions of acoustic field of a regenerator in a thermoacoustic system,a solution of modulating acoustic boundary conditions of a regenerator by two acoustic-drivers was proposes.The acoustic field both in a regenerator and in a resonator was formulated based on Rott Equation,a theoretical model to modulate acoustic boundary conditions of a regenerator was established.Then the relationship between acoustic boundary conditions of a regenerator and the two acoustic drivers was ... |
