Detailed Description

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.

Variations of pressure and temperature from the reference values are taken into account through $ pexp $ and $ texp $

The laminar burning velocity fitting polynomial is:

$ Su = a_{0}(1+a_{1}x+K+..a_{i}x^{i}..+a_{6}x^{6}) (p/p_{ref})^{pexp} (T/T_{ref})^{texp} $

where:

$ a_{i} $ are the polinomial coefficients.

$ pexp $ and $ texp $ are the pressure and temperature factors respectively.

$ x $ is the equivalence ratio.

$ T_{ref} $ and $ p_{ref} $ are the temperature and pressure references for the laminar burning velocity.
