title = "Flow-induced noise from a sharp-edged flat plate using a quasi-periodic CFD-BEM technique",

abstract = "The flow-induced noise from a sharp-edged flat plate submerged in low Mach number flow is predicted using a quasi-periodic computational fluid dynamics (CFD)-boundary element method (BEM) technique. A high-order reconstruction scheme is used to extract acoustic sources based on Lighthill's analogy from the flow field data. Acoustic waves generated by these flow noise sources propagate to and are scattered by the trailing edge of the plate. The fluctuating flow field is obtained using an incompressible CFD solver. A BEM model of the sharp-edged flat plate is used to predict the scattered sound pressure field. A quasi-periodic technique is implemented in the BEM model so that the sound generated by the entire span of the plate can be predicted by modelling only a small spanwise segment. The computed aerodynamic and acoustic results are compared with experimental data obtained using the anechoic wind tunnel at the University of Adelaide.",
