Detailed Description

A constant-heat capacity species thermodynamic property manager class.

This makes the assumption that the heat capacity is a constant. Then, the following relations are used to complete the specification of the thermodynamic functions for the species.

$\frac{c_p(T)}{R} = Cp0\_R$

$\frac{h^0(T)}{RT} = \frac{1}{T} * (h0\_R + (T - T_0) * Cp0\_R)$

$\frac{s^0(T)}{R} = (s0\_R + (log(T) - log(T_0)) * Cp0\_R)$

This parameterization takes 4 input values. These are:

c[0] = (Kelvin)
c[1] = $H_k^o(T_0, p_{ref})$ (J/kmol)
c[2] = $S_k^o(T_0, p_{ref})$ (J/kmol K)
c[3] = ${Cp}_k^o(T_0, p_{ref})$ (J(kmol K)

The multispecies SimpleThermo class makes the same assumptions as this class does.

void updateProperties	(	const doublereal *	tt,
		doublereal *	cp_R,
		doublereal *	h_RT,
		doublereal *	s_R
	)			const `[virtual]`

Update the properties for this species, given a temperature polynomial.

This method is called with a pointer to an array containing the functions of temperature needed by this parameterization, and three pointers to arrays where the computed property values should be written. This method updates only one value in each array.

Form and Length of the temperature polynomial:

m_t[0] = tt;

Parameters:

	tt	Vector of temperature polynomials
	cp_R	Vector of Dimensionless heat capacities. (length m_kk).
	h_RT	Vector of Dimensionless enthalpies. (length m_kk).
	s_R	Vector of Dimensionless entropies. (length m_kk).

Reimplemented from SpeciesThermoInterpType.

void updatePropertiesTemp	(	const doublereal	temp,
		doublereal *	cp_R,
		doublereal *	h_RT,
		doublereal *	s_R
	)			const `[virtual]`

Compute the reference-state property of one species.

Given temperature T in K, this method updates the values of the non-dimensional heat capacity at constant pressure, enthalpy, and entropy, at the reference pressure, Pref of one of the species. The species index is used to reference into the cp_R, h_RT, and s_R arrays.

Parameters:

	temp	Temperature (Kelvin)
	cp_R	Vector of Dimensionless heat capacities. (length m_kk).
	h_RT	Vector of Dimensionless enthalpies. (length m_kk).
	s_R	Vector of Dimensionless entropies. (length m_kk).
