Write: editorial@HydrocarbonProcessing.com Flow-induced noise and vibration in turbocompressors and piping systems are usually flow–velocity dependent and caused by a source or sources internal or external to the machine. These sources are difficult to identify, requiring a knowledge of vortex shedding and system acoustic resonance. This article concentrates on: 1) a theoretical background of vortex generation and excitation of system acoustic response; 2) identifying and solving both actual and
