+Description
+    Solver for compressible premixed/partially-premixed combustion with
+    turbulence modelling.
+
+    Combusting RANS code using the b-Xi two-equation model.
+    Xi may be obtained by either the solution of the Xi transport
+    equation or from an algebraic expression.  Both approaches are
+    based on Gulder's flame speed correlation which has been shown
+    to be appropriate by comparison with the results from the
+    spectral model.
+
+    Strain effects are incorporated directly into the Xi equation
+    but not in the algebraic approximation.  Further work need to be
+    done on this issue, particularly regarding the enhanced removal rate
+    caused by flame compression.  Analysis using results of the spectral
+    model will be required.
+
+    For cases involving very lean Propane flames or other flames which are
+    very strain-sensitive, a transport equation for the laminar flame
+    speed is present.  This equation is derived using heuristic arguments
+    involving the strain time scale and the strain-rate at extinction.
+    the transport velocity is the same as that for the Xi equation.
+
+    For large flames e.g. explosions additional modelling for the flame
+    wrinkling due to surface instabilities may be applied.
+
+    PDR (porosity/distributed resistance) modelling is included to handle
+    regions containing blockages which cannot be resolved by the mesh.

+Description
+
+    Basic sub-grid obstacle flame-wrinkling generation rate coefficient model.
+    Details supplied by J Puttock 2/7/06.
+
+    \f$ G_{sub} \f$ denotes the generation coefficient and it is given by
+
+    \f[
+        G_{sub} = k_{1} /frac{\vert \dwea{\vec{U}} \vert}{L_{obs}}
+                 \frac{/Xi_{{sub}_{eq}}-1}{/Xi_{sub}}
+    \f]
+
+    and the removal:
+
+    \f[
+        - k_{1} /frac{\vert \dwea{\vec{U}} \vert}{L_{sub}}
+        \frac{\Xi_{sub}-1}{\Xi_{sub}}
+    \f]
+
+    Finally, \f$ G_{sub} \f$ is added to generation rate \f$ G_{in} \f$
+    due to the turbulence.
