28 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 exression\&. Both approaches are based on Gulder\(cqs flame speed correlation which has been shown to be appropriate by comparison with the results from the spectral model\&.
30 Strain effects are encorporated 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\&.
32 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\&.
34 For large flames e\&.g\&. explosions additional modelling for the flame wrinkling due to surface instabilities may be applied\&.
36 PDR (porosity/distributed resistance) modelling is included to handle regions containing blockages which cannot be resolved by the mesh\&.
