This seminar will focus on these hybrid RANS-LES methods
and in particular what improvements they offer over pure
RANS and LES approaches. Through several presentations
from experts representing some of the key engineering
sectors (automotive, aerospace & turbo-machinery),
practical examples of these methods will be presented
offering attendees a chance to understand and question if
these methods could be applied to their simulations.

Description:

 

A Guide to Hybrid RANS-LES Methods: Industrial Examples  

and Theory 

 

(Discounted student rate available for this event ) 

 

 

For many companies there is a growing desire to improve  

the accuracy of their CFD simulations, in order to  

improve correlation to experiments and to allow more of  

their design to be undertaken in Computational Fluid  

Dynamics. 

 

This desire for greater accuracy has led many to look at  

Large Eddy Simulation (LES). Whilst LES models can in  

general provide a much better alternative to RANS models  

for unsteady flows, they do so at a much higher cost, so  

much higher that for high-Reynolds numbers flow these  

costs are too great for general purpose calculations.   

 

Hybrid RANS-LES methods offer an attractive alternative,  

where RANS methods are applied in regions of the flow  

which are easy to predict (attached, steady flow) and  

Large Eddy Simulation methods in the more challenging  

separated regions. These methods, if correctly applied,  

can provide close to LES accuracy for a greatly reduced  

computational cost. 

 

This seminar will focus on these hybrid RANS-LES methods  

and in particular what improvements they offer over pure  

RANS and LES approaches. Through several presentations  

from experts representing some of the key engineering  

sectors (automotive, aerospace & turbo-machinery),  

practical examples of these methods will be presented  

offering attendees a chance to understand and question if  

these methods could be applied to their simulations. 

 

In addition to more applied talks, there will be several  

talks from globally recognized experts on hybrid RANS-LES  

methods, who will talk of the latest developments and  

bring concrete examples of where hybrid RANS-LES has  

brought about improvements. 

 

The major CFD code vendors will also be represented at  

this seminar, allowing attendees to see the full range of  

options open to their company or institution. 

 

With this combination of activities, delegates will leave  

the seminar having a better understanding both of the  

theory behind hybrid RANS-LES methods but also concrete  

industrial examples of their real-life use. 

 

 

 

Who Should Attend? 

 

This seminar will be of interest to academics as well as  

practitioners and industrial users of commercial CFD  

codes. The focus of the talks will be on hybrid RANS-LES  

methods, but people with a general interest in the  

application of CFD to complex real-life problems will  

also benefit from attending this seminar.
