Validation Method for Finite-Element Modeling of Acoustic Re-emission of Bodies in the Turbulent Fluid Flow

Abstract

In this paper, we generalize the previously developed method of finite element modeling of the noise emission produced by inhomogeneities of bodies in a turbulent flow for the prismatic mesh discretization of a compressible fluid. The method was validated based on well-known analytical solutions for prediction problems of noise emission produced when two-dimensional and three-dimensional streamlining cylindrical or spherical bodies that are small in comparison with the acoustic wavelength.
