Announcements NAFEMS will host a Computational Aeroacoustics Seminar taking place on 20th November 2013 at Heritage Motor Centre in Gaydon, UK.

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 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.
