Class
    Foam::XiModels::algebraic

Description
    Simple algebraic model for Xi based on Gulders correlation
    with a linear correction function to give a plausible profile for Xi.
    See report TR/HGW/10 for details on the Weller two equations model.
    See \link XiModel.H \endlink for more details on flame wrinkling modelling.
