Strong tonal noise can be found on the main steam lines of power plants. The source of noise was identified to be located at the gate valves present on the steam lines. Analysis of on-site measurements showed that the source of noise was due to the cavity that forms the valve seat at the bottom of the valve body. The valve in its open position is then composed of this bottom cavity over which an unstable shear layer develops but also of the top cavity where the gate is stored in open position… CONTINUE READING
