Detailed Description

Differential SGS Stress Equation Model for incompressible and compressible flows.

Reference:

    Deardorff, J. W. (1973).
    The use of subgrid transport equations in a three-dimensional model
    of atmospheric turbulence.
    Journal of Fluids Engineering, 95(3), 429-438.

This SGS model uses a full balance equation for the SGS stress tensor to simulate the behaviour of B.

This implementation is as described in the above paper except that the triple correlation model of Donaldson is replaced with the generalized gradient diffusion model of Daly and Harlow:

    Daly, B. J., & Harlow, F. H. (1970).
    Transport equations in turbulence.
    Physics of Fluids (1958-1988), 13(11), 2634-2649.

with the default value for the coefficient Cs of 0.25 from

    Launder, B. E., Reece, G. J., & Rodi, W. (1975).
    Progress in the development of a Reynolds-stress turbulence closure.
    Journal of fluid mechanics, 68(03), 537-566.
