Abstract

The initiation of narrow-band pressure fluctuations in the duct of a pipeline gas-compression station when the flow is turned near a blind-ended cavity was studied in a wind tunnel. The flow pattern under consideration was estimated from visualization of the flow in a water channel using the hydraulic analogy technique. It is believed that the high-intensity narrow-band pressure fluctuations observed in the flow result from the instability and regular rearrangement of large-scale vortex structures in the blind-ended cavity.
