摘要/Abstract

摘要： 炉内换热器结构类似于声子晶体，基于声子晶体理论，采用数值计算与软件模拟得到管阵列中声源不同方向的声传播特性，并将两种方法所得结果进行对比分析，研究声源在管阵列中不同位置处的辐射特性.结果表明：声指向性特性与声源通过管排数量，声源频率是否处在声波禁带有关.

关键词: 管阵列, 声子晶体, 声辐射, 带隙结构

Abstract: Based on study of sound propagation characteristics in periodic tube array, we investigate acoustic radiation characteristics in power station tube arrays. The heat exchanger structure in boiler is similar to phononic crystal. Different location in tube arrays acoustic radiation characteristics is studied. It shows that acoustic radiation directivity not only have relation with tube row number, but also have relation with frequency in acoustic band gap.

Key words: tube array, phononic crystal, acoustic radiation, band-gap structure
