Class
    Foam::XiModels::equilibrium
 
Description
    Simple equilibrium model for flame wrinkling \c Xi
 
    Note that this model does not guarantee that the brush will attain a stable
    thickness in unbounded propagation which would require a \c Xi distribution
    through the flame, lower at the front and higher at the rear, see
    Foam::XiEqModels::linearEquilibrium or Foam::XiEqModels::cubicEquilibrium
    for alternative equilibrium models which provide this.
 
    See Foam::XiModel for more details on flame wrinkling modelling.
