Description
|
|
Implementation of the k-omega-SST-DES turbulence model for
|
|
incompressible and compressible flows.
|
|
|
|
DES model described in:
|
|
\verbatim
|
|
Menter, F. R., Kuntz, M., and Langtry, R. (2003).
|
|
Ten Years of Industrial Experience with the SST Turbulence Model.
|
|
Turbulence, Heat and Mass Transfer 4, ed: K. Hanjalic, Y. Nagano,
|
|
& M. Tummers, Begell House, Inc., 625 - 632.
|
|
\endverbatim
|
|
|
|
Optional support for zonal filtering based on F1 or F2 is provided as
|
|
described in the paper.
|
|
|
|
For further details of the implementation of the base k-omega-SST model
|
|
see Foam::kOmegaSST.
