VNoise provides a series of fully integrated tools that can be applied to a
wide range of aeroacoustic simulations. All the tools are integrated in a
common framework that permit to afford different simulation domains with a
unified approach. Different kind of simulations can be performed following a
unified simulation path, and adopting the most appropriate module at each step.
The overall approach ensure a great flexibility and efficiency and makes
possible for the first time to perform complex aero-acoustic calculations at an
industrial level, not only at the analysis but also at the design stage.
The overall process can be subdivided in 4 independent steps:
Acoustic Domains: Definition of acoustic meshes for the domains
enclosing the different aeroacoustic sources and the propagation domain.
Source Evaluation: Evaluation of the aeroacoustic sources for each
source domain with the proper tool.
Propagation:Assembling of all the sources in the overall propagation
Different tools can be used for each step in relation to the specific problem to
CFD: Different tools can be used typically RANS or URANS but also LES/DES
analyses can be accomodated if required. Virtually all commercial CFD software
are supported with the proper interfaces.
Flow Noise: Extract full spectrum of aeroacoustic
sources from steady CFD RANS analyses
FWH Solver: Noise radiation from rotating blades,
BEM: Boundary element analysis for the convective
FEM: Finite Element analysis for propagation in both
uniform and non uniform flows
Both BEM and FEM can eventually include structural coupling for completly
coupled aero-vibro-acoustic analyses
