NAME

       freefoam-engine - Solver for internal combustion engines.

SYNOPSIS

       freefoam engine [-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.
