Acoustic Noncompactness of a Beveled Trailing Edge Using Incompressible Flow Source Data

Noncompactness should be included in the source term when applying an integral solution based on an aeroacoustic analogy, such as Curle’s analogy. An easy solution to include this acoustical information would be by applying a high-fidelity compressible flow solution using high-order schemes with low dissipation and dispersion. This will include both the incident and scattered pressure effects. A study proposes an acoustic correction for when the surface source term is lacking acoustic scattered information. It presents acoustic results from a 25 deg beveled trailing edge, where the flow data are obtained from an open-source transient, finite-volume-based computational fluid dynamic solution of the incompressible Navier–Stokes equations.
