This is the first one-day NAFEMS Seminar devoted to
Computational Aeroacoustics and CAE methods for noise
propagation and transmission, where Invited speakers from
industry, academia and the leading software providers will
give an insight into noise issues and computational tools
applied to noise abatement in up-front design.

Description:

 

Many industry sectors are facing increasing pressure from  

customers to reduce flow noise and its transmission to the  

interior environment or propagated externally to by  

passers. CAE is proving to be an increasingly valuable tool  

to help understand the flow noise generation propagation  

and transmission mechanisms. Consequently, engineers are  

able to design against them either by reducing the source  

or minimising it propagation in the  

aerodynamic/hydrodynamic domain and transmission through  

structures. 

 

In this seminar, our presenters will cover all the  

principle methods for predicting aeroacoustic noise  

generation mechanisms;tonal and broadband, arising from  

rotating machinery, coherent flow structures and  

turbulence; from stochastic models to fully wall-resolved  

large-eddy simulation (LES). 

 

The traditional methods for computational aeroacoustics  

will be covered, including the use of aeroacoustic  

analogies up to the direct simulation of noise. 

 

Case studies from the automotive, aerospace, marine, power  

generation and many more sectors will illustrate the use of  

Computational Fluid Dynamics (CFD) in the time domain, and  

also frequency based modelling using Boundary Element  

Methods (BEM), Finite Element Methods (FEM) and Statistical  

Energy Analysis (SEA). 

 

A detailed agenda will be provided in due course. 

 

The programme will follow three main tranches;  

 

* modelling of the flow noise generation mechanisms,  

 

* propagation and transmission methodologies, and 

 

* combined studies in aero-vibro acoustics 

 

When registering please indicate which (any or all) of the  

tranches are most relevant to you.
