Janafspecie

Represents a chemical species using JANAF thermodynamic data.
class FELiCS.Equation.Reactions.janafspecie.Janafspecie(W, Tlow, Thigh, Tcommon, lowCpCoeffs, highCpCoeffs, P)#

Represents a chemical species using JANAF thermodynamic data.

This class models the thermodynamic properties of a species based on JANAF polynomial coefficients for specific heat capacity and entropy over a range of temperatures.
