Detailed Description

Basic sub-grid obstacle flame-wrinking generation rate coefficient model. Details supplied by J Puttock 2/7/06.

$ G_{sub} $ denotes the generation coefficient and it is given by

\[ G_{sub} = k_{1} /frac{\vert \dwea{\vec{U}} \vert}{L_{obs}} \frac{/Xi_{{sub}_{eq}}-1}{/Xi_{sub}} \]

and the removal:

\[ - k_{1} /frac{\vert \dwea{\vec{U}} \vert}{L_{sub}} \frac{\Xi_{sub}-1}{\Xi_{sub}} \]

Finally, $ G_{sub} $ is added to generation rate $ G_{in} $ due to the turbulence.
