| 摘 要： | 文献1]报道了本混合型热声发动机存在两个振动模态--高频模态和低频模态.在试验上成功地获得了稳定的高频模态.首次对这两个模态的本征特性及其演变规律进行了详细的对比分析,发现这是两个显著不同的热声模态.在理论上对该型热机进行了初步的探讨,分析了该模态行为对系统的稳定性的重要影响,并指出了这种效应的工程意义.

| Abstract: | Two modes in a hybird thermoacoustic engine, high frequency mode and low frequency mode, have been reported in Ref.1. The stable high frequercy mode have been successfully gained through test.The characteristics and development rule of the two modes have detaily been compared and analyzed in the first time,it kas been fownd that they are two notable different thermoacoustic modes.This hgbird thermoacoustic engine is initially explored in theory.The important influence of the mode action of this system to the stability of it has been analyzed.This effective engineering meaning has been given in this paper. |
