Empirical study of flat plate trailing edge flow and noise
This paper presents results of an empirical study on the flow and noise generated by the trailing edge of a flat plate encountering low turbulence fluid flow. Simultaneous measurements of flow and far-field noise data have been taken in an anechoic wind tunnel at the University of Adelaide. Velocity data about the trailing edge and in the wake have been measured using hot-wire anemometry. These...
متن کاملStatistical Estimation of Turbulent Trailing Edge Noise
A new computational aeroacoustic model suitable for the prediction of turbulent airfoil trailing edge noise is presented. The method (known as the RANS based Statistical Noise Model or RSNM) combines numerically generated, mean turbulence information with a Green’s function for a semi-infinite half-plane to generate a far-field acoustic auto-spectrum. As a preliminary application of the method,...
متن کاملComputation of Trailing Edge Noise with a Discontinuous Galerkin Method
Trailing edge noise of a semi-infinite, thin, flat plate situated in low Mach number flow is computed in two spatial dimensions. The Acoustic Perturbation Equations (APE), which are employed as governing equations, are discretized via a Discontinuous Galerkin Method (DGM). Results are compared with theory and Finite Difference (FD) computations. Next to the radiated sound field, special attenti...
