Based on the Twersky s sound scattering theory and the grating diffraction theory,the sound transmission behaviors of a tube row in boilers are studied.
基于Twersky声波散射理论和光栅衍射理论,对炉内单排换热器管阵列的声传输特性进行了研究,分析了管排阵列对入射声波的反射、透射和衍射的物理机制,给出了计算管排阵列声透射与反射系数的数学模型,数值研究了管排阵列对声波的反射与透射系数随管间距、声波频率等参数变化的关系曲线,揭示了单排管阵列对声波传播具有截止和导通作用,并且其截止带和导通带的位置与管阵列结构参数和炉内温度有关。
