Detailed Description
PhaseCombo_Interaction is a derived class of GibbsExcessVPSSTP that employs the Margules approximation for the excess gibbs free energy while eliminating the entropy of mixing term.
PhaseCombo_Interaction derives from class GibbsExcessVPSSTP which is derived from VPStandardStateTP, and overloads the virtual methods defined there with ones that use expressions appropriate for the Margules Excess gibbs free energy approximation. The reader should refer to the MargulesVPSSTP class for information on that class. This class in addition adds a term to the activity coefficient that eliminates the ideal solution mixing term within the chemical potential. This is a very radical thing to do, but it is supported by experimental evidence under some conditions.
The independent unknowns are pressure, temperature, and mass fraction.
Several concepts are introduced. The first concept is that there are temporary variables for holding the species standard state values of Cp, H, S, G, and V at the last temperature and pressure called. These functions are not recalculated if a new call is made using the previous temperature and pressure. Currently, these variables and the calculation method are handled by the VPSSMgr class, for which VPStandardStateTP owns a pointer to.
To support the above functionality, pressure and temperature variables, m_plast_ss and m_tlast_ss, are kept which store the last pressure and temperature used in the evaluation of standard state properties.
This class is introduced to represent specific conditions observed in thermal batteries. HOwever, it may be physically motivated to represent conditions where there may be a mixture of compounds that are not "mixed" at the molecular level. Therefore, there is no mixing term.
The lack of a mixing term has profound effects. First, the mole fraction of a species can now be identically zero due to thermodynamic considerations. The phase behaves more like a series of phases. That's why we named it PhaseCombo.
Specification of Species Standard State Properties
All species are defined to have standard states that depend upon both the temperature and the pressure. The Margules approximation assumes symmetric standard states, where all of the standard state assume that the species are in pure component states at the temperature and pressure of the solution. I don't think it prevents, however, some species from being dilute in the solution.
Specification of Solution Thermodynamic Properties
The molar excess Gibbs free energy is given by the following formula which is a sum over interactions i. Each of the interactions are binary interactions involving two of the species in the phase, denoted, Ai and Bi. This is the generalization of the Margules formulation for a phase that has more than 2 species. The second term in the excess gibbs free energy is a negation of the ideal solution's mixing term.
\[ G^E = \sum_i \left( H_{Ei} - T S_{Ei} \right) - \sum_i \left( n_i R T \ln{X_i} \right) \]
\[ H^E_i = n X_{Ai} X_{Bi} \left( h_{o,i} + h_{1,i} X_{Bi} \right) \]
\[ S^E_i = n X_{Ai} X_{Bi} \left( s_{o,i} + s_{1,i} X_{Bi} \right) \]
where n is the total moles in the solution.
The activity of a species defined in the phase is given by an excess Gibbs free energy formulation.
\[ a_k = \gamma_k X_k \]
where
\[ R T \ln( \gamma_k )= \frac{d(n G^E)}{d(n_k)}\Bigg|_{n_i} \]
Taking the derivatives results in the following expression
\[ R T \ln( \gamma_k )= \sum_i \left( \left( \delta_{Ai,k} X_{Bi} + \delta_{Bi,k} X_{Ai} - X_{Ai} X_{Bi} \right) \left( g^E_{o,i} + g^E_{1,i} X_{Bi} \right) + \left( \delta_{Bi,k} - X_{Bi} \right) X_{Ai} X_{Bi} g^E_{1,i} \right) - RT \ln{X_k} \]
where \( g^E_{o,i} = h_{o,i} - T s_{o,i} \) and \( g^E_{1,i} = h_{1,i} - T s_{1,i} \) and where \( X_k \) is the mole fraction of species k.
This object inherits from the class VPStandardStateTP. Therefore, the specification and calculation of all standard state and reference state values are handled at that level. Various functional forms for the standard state are permissible. The chemical potential for species k is equal to
\[ \mu_k(T,P) = \mu^o_k(T, P) + R T \ln(\gamma_k X_k) \]
The partial molar entropy for species k is given by the following relation,
\[ \tilde{s}_k(T,P) = s^o_k(T,P) - R \ln( \gamma_k X_k ) - R T \frac{d \ln(\gamma_k) }{dT} \]
The partial molar enthalpy for species k is given by
\[ \tilde{h}_k(T,P) = h^o_k(T,P) - R T^2 \frac{d \ln(\gamma_k)}{dT} \]
The partial molar volume for species k is
\[ \tilde V_k(T,P) = V^o_k(T,P) + R T \frac{d \ln(\gamma_k) }{dP} \]
The partial molar Heat Capacity for species k is
\[ \tilde{C}_{p,k}(T,P) = C^o_{p,k}(T,P) - 2 R T \frac{d \ln( \gamma_k )}{dT} - R T^2 \frac{d^2 \ln(\gamma_k) }{{dT}^2} \]
Application within Kinetics Managers
\( C^a_k\) are defined such that \( a_k = C^a_k / C^s_k, \) where \( C^s_k \) is a standard concentration defined below and \( a_k \) are activities used in the thermodynamic functions. These activity (or generalized) concentrations are used by kinetics manager classes to compute the forward and reverse rates of elementary reactions. The activity concentration, \( C^a_k \),is given by the following expression.
\[ C^a_k = C^s_k X_k = \frac{P}{R T} X_k \]
The standard concentration for species k is independent of k and equal to
\[ C^s_k = C^s = \frac{P}{R T} \]
For example, a bulk-phase binary gas reaction between species j and k, producing a new gas species l would have the following equation for its rate of progress variable, \( R^1 \), which has units of kmol m-3 s-1.
\[ R^1 = k^1 C_j^a C_k^a = k^1 (C^s a_j) (C^s a_k) \]
where
\[ C_j^a = C^s a_j \mbox{\quad and \quad} C_k^a = C^s a_k \]
\( C_j^a \) is the activity concentration of species j, and \( C_k^a \) is the activity concentration of species k. \( C^s \) is the standard concentration. \( a_j \) is the activity of species j which is equal to the mole fraction of j.
The reverse rate constant can then be obtained from the law of microscopic reversibility and the equilibrium expression for the system.
\[ \frac{a_j a_k}{ a_l} = K_a^{o,1} = \exp(\frac{\mu^o_l - \mu^o_j - \mu^o_k}{R T} ) \]
\( K_a^{o,1} \) is the dimensionless form of the equilibrium constant, associated with the pressure dependent standard states \( \mu^o_l(T,P) \) and their associated activities, \( a_l \), repeated here:
\[ \mu_l(T,P) = \mu^o_l(T, P) + R T \log(a_l) \]
We can switch over to expressing the equilibrium constant in terms of the reference state chemical potentials
\[ K_a^{o,1} = \exp(\frac{\mu^{ref}_l - \mu^{ref}_j - \mu^{ref}_k}{R T} ) * \frac{P_{ref}}{P} \]
The concentration equilibrium constant, \( K_c \), may be obtained by changing over to activity concentrations. When this is done:
\[ \frac{C^a_j C^a_k}{ C^a_l} = C^o K_a^{o,1} = K_c^1 = \exp(\frac{\mu^{ref}_l - \mu^{ref}_j - \mu^{ref}_k}{R T} ) * \frac{P_{ref}}{RT} \]
Kinetics managers will calculate the concentration equilibrium constant, \( K_c \), using the second and third part of the above expression as a definition for the concentration equilibrium constant.
For completeness, the pressure equilibrium constant may be obtained as well
\[ \frac{P_j P_k}{ P_l P_{ref}} = K_p^1 = \exp(\frac{\mu^{ref}_l - \mu^{ref}_j - \mu^{ref}_k}{R T} ) \]
\( K_p \) is the simplest form of the equilibrium constant for ideal gases. However, it isn't necessarily the simplest form of the equilibrium constant for other types of phases; \( K_c \) is used instead because it is completely general.
The reverse rate of progress may be written down as
\[ R^{-1} = k^{-1} C_l^a = k^{-1} (C^o a_l) \]
where we can use the concept of microscopic reversibility to write the reverse rate constant in terms of the forward reate constant and the concentration equilibrium constant, \( K_c \).
\[ k^{-1} = k^1 K^1_c \]
\(k^{-1} \) has units of s-1.

This doesn't do much more than initialize constants with default values for water at 25C. Water molecular weight comes from the default elements.xml file. It actually differs slightly from the IAPWS95 value of 18.015268. However, density conservation and therefore element conservation is the more important principle to follow.

Initialize. This method is provided to allow subclasses to perform any initialization required after all species have been added. For example, it might be used to resize internal work arrays that must have an entry for each species. The base class implementation does nothing, and subclasses that do not require initialization do not need to overload this method. When importing a CTML phase description, this method is called just prior to returning from function importPhase.
