Detailed Description

Barin-Knacke-Kubachewski single parameter set for pure component single phase enthalpy properties according to I.Barin O.Knacke O.Kubachewski "Thermodynamical properties of inorganic substances" Berlin 1977 cp(T) = -c - 2*d*T - 6*e*T^2 - 12*f*T^3 - 2*g/T^2 - 6*h/T^3 J/kmol-K h(T) = a + integrate(cp(T), T) J/kmol s(T) = -(b + c) + integrate(cp(T)/T, T) J/kmol-K g(T) = h(T) - T * s(T) = a + integrate(cp(T), T) - T * (-(b + c) + integrate(cp(T)/T, T)) J/kmol

Member Enumeration Documentation

property

enum ParameterBkk::property

properties that can be calculated

Enumerator
cp_	specific heat
h_	enthalpy
s_	entropy
g_	Gibbs free energy.

Constructor & Destructor Documentation

ParameterBkk()

		double	A,
		double	B,
		double	C,
		double	D,
		double	E,

xmax	upper temperature limit for the validity of the properties
A	heat of formation
B	entropy contribution coefficient
C	negative of the specific heat at the reference temperature
D	linear term for the specific heat
E	quadratic term for the specific heat
F	cubic term for the specific heat
G	rational quadratic term for the specific heat
H	rational cubic term for the specific heat
