A Guide to Hybrid RANS-LES Methods: Industrial Examples and Theory
|
|
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: |
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.
