Class
    Foam::laminarFlameSpeedModels::Gulder
 
Description
    Laminar flame speed obtained from Gulder's correlation
 
    with optional support for EGR (exhaust gas recirculation) if the \c egr
    mass-fraction field is available.
 
    Reference:
    \verbatim
        Gülder, Ö. L. (1984).
        Correlations of laminar combustion data for alternative SI engine fuels
        (No. 841000). SAE technical paper.
    \endverbatim
 
    Note: the EGR \c f coefficient multiplies the \c egr mass-fraction, not the
    mole-fraction as stated in the paper so must be set accordingly.
