Large Eddy Simulation Awareness Workshop - AGENDA ANNOUNCED!
This seminar will be of interest to practitioners and Industrial users of commercial CFD codes in the main, familiarity with standard RANS turbulence modelling such as k-epsilon models will be a prerequisite as RANS will serve as the stepping stone to the day.
Date: November 8, 2010

Application Areas: General CFD
Type of Event: Seminar, International

Large Eddy Simulation, LES, is fast becoming more readily 
available in the major commercial CFD codes and from the 
internet. Computer power is increasing rapidly too, at an 
affordable cost, making it potentially easier to run 
simulations using such methods. 

More CFD users are therefore becoming interested in 
learning about this method and its applications. While LES 
is very powerful it also requires some care to be used 
properly, as it is conceptually very different from RANS, 
the workhorse of industrial CFD. 

This seminar will start by establishing and comparing the 
fundamental assumptions supporting RANS and LES and, in 
doing so, will highlight what the true potential of LES is, 
as well as its limitations. It will continue by way of a 
short review of the most common LES formulations before 
allowing time for the presentation of two key applications. 
The software and hardware requirement of running a LES 
simulation will also be reviewed as we move towards the end 
of the day to add a cost dimension to the information pack 

More affordable alternatives, so-called hybrid methods, 
based on LES principles, such as Detached Eddy Simulation 
(DES), will also be presented together with examples of 
their applications and own limitations. A brief question 
and answer session will summarise the day. 

With this combination of activities, delegate will leave 
the seminar having a better understanding of what LES can 
offer, to which problems it is suited and what constraints 
and costs it bears.
