NAME

       freefoam-Xi - Solver for compressible premixed/partially-premixed combustion with
       turbulence modelling.

SYNOPSIS

       freefoam Xi [-parallel] [-srcDoc] [-case <dir>] [-doc] [-help]

DESCRIPTION

       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’s flame speed correlation which has been shown to be appropriate by
       comparison with the results from the spectral model.

       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.

       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.
