Laminar flame speed obtained from the SCOPE correlation.
Seven parameters are specified in terms of polynomial functions of stoichiometry. Two polynomials are fitted, covering different parts of the flammable range. If the mixture is outside the fitted range, linear interpolation is used between the extreme of the polynomio and the upper or lower flammable limit with the Markstein number constant.
