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