The structural vibration and fluid-borne noise induced by turbulent flow through a 90 piping elbow is studied and the effect of guide vanes in different positions installed at the elbow on the flow-induced vibration and flow-induced noise is investigated. Large Eddy Simulation (LES) model is adopted to solve for time varying pressure and velocity fields. The structural vibration is investigated based on a fluid structure interaction (FSI) code using harmonic response analysis. The computation of hydrodynamic noise is based on a hybrid LES/Lighthill's acoustic analogy method and sound sources are solved as volume sources in commercial software ACTRAN. The numerical results indicate that the guide vane at the right location is effective in reducing vibration and flow-induced noise in the 90 piping elbow with water. The ideal position of the guide vane is determined and some useful engineering conclusions are drawn. (C) 2014 Elsevier Ltd. All rights reserved.
