Detailed Description

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

SpalartAllmarasDES DES turbulence model for incompressible and compressible flows.

    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.

Including the low Reynolds number correction documented in

    Spalart, P. R., Deck, S., Shur, M.L., Squires, K.D., Strelets, M.Kh,

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.
