Prediction of Broadband Noise from Two Square Cylinders in Tandem Arrangement Using a Combined DDES/FWH Approach

  • Conference paper

Part of the book series: Notes on Numerical Fluid Mechanics and Multidisciplinary Design ((NNFM,volume 125))

Abstract

A combined CFD/CAA method is used to study the turbulent flow and the flow-induced noise generated by two square cylinders in tandem arrangement. The selected test case activates noise generation mechanisms which are typical of realistic landing gear struts under approach conditions and the employed prediction methods prove capable of capturing all relevant physical effects. The nearfield and farfield results are discussed in close comparison to experimental data.
