title = "Semi-empirical impedance model of perforated plate under grazing flow",
abstract = "A semi-empirical impedance formula of a circular orifice under grazing flow is derived, based on a linearized potential flow model. The effect of boundary layer is considered by introducing the convection speed of vorticity which is assumed to be a function of the dimensionless boundary layer thickness. Asymptotic expression of the impedance at low Strouhal number is acquired by the method of perturbation, while the impedance at large Strouhal number can be well approximated by that without grazing flow. The model predictions achieve reasonable agreement with the data available in a previous experimental investigation.",
