Detailed Description

template<class BasicTurbulenceModel>
class Foam::LESModels::SpalartAllmarasDES< BasicTurbulenceModel >

SpalartAllmarasDES DES turbulence model for incompressible and compressible flows.

Reference:

    Spalart, P. R., Jou, W. H., Strelets, M., & Allmaras, S. R. (1997).
    Comments on the feasibility of LES for wings, and on a hybrid
    RANS/LES approach.
    Advances in DNS/LES, 1, 4-8.

Including the low Reynolds number correction documented in

    Spalart, P. R., Deck, S., Shur, M.L., Squires, K.D., Strelets, M.Kh,
    Travin, A. (2006).
    A new version of detached-eddy simulation, resistant to ambiguous grid
    densities.
    Theor. Comput. Fluid Dyn., 20, 181-195.

Note: The default value of the DES constant implemented was calibrated for OpenFOAM using decaying isotropic turbulence and agrees with the value suggested in the reference publication.
