AB - The authors have performed laboratory modeling of noise-emission processes in turbulent flows of the heat-transfer agent in shutoff and control valves of a pipeline. Experiments were conducted on an aeroacoustic bench consisting of a model of the flow chamber of shutoff and control valves (parallelepiped), inlet and outlet tubes, an exhaust fan, and a baffle chamber. Parallel measurements of velocity fields were performed by the PIV method, and of acoustic characteristics, with a microphone. The experiments were conducted with different widths of the gaps between the tubes in the flow-chamber model. At certain values of the gaps, tone sounding was recorded at frequencies of 340 and 680 Hz by the microphone, which, as subsequently shown by results of the velocity-field measurements, is a consequence of the self-oscillating flow regime occurring with a periodic separation of vortices whose scale is comparable with the gap width in the flow chamber.
