NAFEMS Computational Aeroacoustics Seminar, Nov 2013, United Kingdom

Posted By: Jo Davenport
Date:Mon, 23 Sep 2013, 3:14 p.m.

United Kingdom, November 20, 2013

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.



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

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.
