中文摘要
翻译
在许多工程应用中，会遇到含有钝体簇的管道，例如热交换器和锅炉的管束，压气机叶片的级联，管道中的导叶/转向叶片和径向扩散器，不幸的操作条件可能导致流动激发的声学共振。当热交换器管束发生声共振时，可能会产生剧烈的噪声和/或管的过度振动。这通常会导致热交换器的大面积损坏和/或完全失效。由于这种现象尚未被完全理解，它可能是危险的不可预测的。
英文摘要
In many engineering applications where ducts containing clusters of bluff bodies are encountered, such as tube bundles of heat exchangers and boilers, cascades of compressor blades and guide/turning vanes in ducts and radial diffusers, unfortunate operating conditions could lead to flow-excited acoustic resonance. When acoustic resonance materialize in heat exchanger tube bundles, the generation of acute noise and/or excessive vibration of the tubes could occur. This will often lead to extensive damage and/or complete failure of heat exchangers. Since this phenomenon is not yet fully understood, it can be dangerously unpredictable.
