Hybrid RANS-LES Methods for Industrial CFD, Jun 2012, United States

Posted By: Kris Kennedy
Date:Wed, 16 May 2012, 11:03 p.m.

United States, June 18, 2012

National Institute of Aerospace presents the ERCOFTAC
organized course to the US Computatonal Fluid Dynamics
(CFD) community. This course has been organized by Dr.
Charles Mocket and the ERCOFTAC Coordinator, Dr. Richard



Turbulence is one of the last remaining challenges in the
simulation of fluid flows. Although RANS (Reynolds-Averaged
Navier Stokes) turbulence models are still very widely
used, these approaches are being slowly supplanted by Large
Eddy Simulation (LES). However, LES is prohibitively
expensive for the industrial simulation of wallbounded
flows, especially at high Reynolds number. As a result, a
family of Hybrid RANS-LES techniques, of which Detached
Eddy Simulation (DES) is one member, are being increasingly
used for the modelling of flow in and around complex
geometries. Due to the current lack of readily-available
expert guidance on the application of Hybrid RANS-LES
techniques, and the emergence of DES as one of the tools of
the trade, ERCOFTAC has drawn upon its worldwide network of
academic and industrial experts to provide a training
course aimed at an industrial CFD audience and relevant to
a wide range of industry sectors including: Aerospace,
automotive, chemical and process, civil and built
environment, power generation and the wider engineering

Specifically, this course aims to provide:

An overview of turbulence modelling.

A firm foundation in the theory and ideas underlying,
RANS, LES and Hybrid RANS-LES techniques.

Recommendation and guidance for the appropriate and
effective application of Hybrid RANS-LES. Examples from
real-world engineering simulations, using the DES class of

The course fee will be $1200. The fee includes course
registration, course material, lunches, refreshment and the
course dinner held at the Virginia Air and Space Center.
Please note that accommodations are not included in the
course fee.
