Detailed Description

Gibson and Dafa'Alla's q-zeta two-equation low-Re turbulence model for incompressible flows.

This turbulence model is described in: 

    Dafa'Alla, A.A., Juntasaro, E. & Gibson, M.M. (1996).
    Calculation of oscillating boundary layers with the
    q-zeta turbulence model.
    Engineering Turbulence Modelling and Experiments 3:
    Proceedings of the Third International Symposium,
    Crete, Greece, May 27-29, 141.

which is a development of the original q-zeta model described in: 

    Gibson, M. M., & Dafa'Alla, A. A. (1995).
    Two-equation model for turbulent wall flow.
    AIAA journal, 33(8), 1514-1518.
