FlowNoise is a VNoise module that permit to evaluate the aeroacoustic noise
generated by turbulence. Typical applications include for example:
The Flow-Noise Module requires as an input a RANS or URANS analysis and perform
a synthetic reconstruction of the turbulence spectrum starting from mean values
of turbulence kinetic energy and dissipation.
Duct Noise: Noise egenerated by flow in ducts due to presence of
obstructions, valves, bending ...
FAN Noise: non tonal component of fan noise.
TBL Noise: Turbulent Boundary layer Noise.
Airframe: Noise generated by aircraft high lift devices, and
|FlowNoise is a component of the
VNoise integrated aeroacoustic suite, and when coupled with the
FWH-Solver and the FEM/BEM solver for the convective Helmholtz equation
constitute a poweful tool that can be applied in a wide range of different
A typical application is reported below for the case of a duct with a 45°
degree valve that generate noise in presence of flow. The spectra at 2
different microphones position outside the duct are reported below where the
FlowNoise results are compared with experimental measuraments.
