Study on a countermeasure for high level sound generated from boiler tube bank duct using walls made of perforated plate (Grasp critical aperture ratio and influence of cavity volume on suppression effect)
Karman vortex shedding occurs when the gas passes through the duct with tube bank of the heat exchangers, such as gas heaters and boilers. Very high level sound in called “self-sustained tones” occurs due to the interference of the vortex and the sound field in the duct. In general, baffle plates ar...
