Detailed Description

Class LiquidTransport implements models for transport properties for liquid phases.

Liquid Transport is set up with some flexibility in this class. Transport properties like viscosity and thermal conductivity are allowed flexibility within the constraints of the LiquidTransportProperty and LiquidTransportInteractions classes. For species diffusion, the LiquidTransport class focuses on the Stefan-Maxwell equation to determine the diffusion velocities. Other options for liquid diffusion include solvent-dominated diffusion, and a class SolventTransport should be forthcoming.

The class LiquidTransport has several roles.

It brings together the individual species transport properties, expressed as subclasses of LTPspecies (Liquid Transport Properties of Species) through LiquidTransportData, with models for the composition dependence of liquid transport properties expressed as subclasses of LiquidTranInteraction (mixing rules) through LiquidTransportParams. Calculating mixture properties generally consists of calling the getMixTansProp member of LiquidTranInteraction by passing a vector of LTPSpecies
It calculates the bulk velocity \( \vec{v} \) and individual species diffusion velocities, \( \vec{V_i} \) using the Stefan-Maxwell equations. It is possible to set a flag to calculate relative to a mass-averaged bulk velocity, relative to a mole-averaged bulk velocity or relative to a single species velocity using the <velocityBasis basis="mass">, <velocityBasis basis="mass">, or <velocityBasis basis="Cl-"> keyword. Mass-averaged velocities are the default for which the diffusion velocities satisfy
\[ \sum_{i} Y_i \vec{V_i} = 0 \]
for mass fraction \( Y_i \). For mole-averaged velocities
\[ \sum_{i} X_i \vec{V_i} = 0 \]
for mole fraction \( X_i \). or
\[ \vec{V_i} = 0 \]
for reference species \( i \).
It provides access to a number of derived quantities related to transport properties as described in the various methods below.

Within LiquidTransport, the state is presumed to be defined in terms of the species mole fraction, temperature and pressure. Charged species are expected and quantities like the electric current are computed based on a combined electrochemcial potential.

void selfDiffusion ( doublereal *const selfDiff )

virtual

Returns the self diffusion coefficients of the species in the phase.

Has size of nsp(coeffs)

The self diffusion coefficient is the diffusion coefficient of a tracer species at the current temperature and composition of the species. Therefore, the dilute limit of transport is assumed for the tracer species. The effective formula may be calculated from the stefan-maxwell formulation by adding another row for the tracer species, assigning all D's to be equal to the respective species D's, and then taking the limit as the tracer species mole fraction goes to zero. The corresponding flux equation for the tracer species k in units of kmol m-2 s-1 is.

\[ J_k = - D^{sd}_k \frac{C_k}{R T} \nabla \mu_k \]

The derivative is taken at constant T and P.

The self diffusion calculation is handled by subclasses of LiquidTranInteraction as specified in the input file. These in turn employ subclasses of LTPspecies to determine the individual species self diffusion coeffs.

Parameters

selfDiff Vector of self-diffusion coefficients Length = number of species in phase units = m**2 s-1

void getBinaryDiffCoeffs	(	const size_t	ld,
		doublereal *const	d
	)

virtual

Returns the binary diffusion coefficients.

The binary diffusion coefficients are specified in the input file through the LiquidTransportInteractions class. These are the binary interaction coefficients employed in the Stefan-Maxwell equation.

Parameters

ld	number of species in system
d	vector of binary diffusion coefficients units = m2 s-1. length = ld*ld = (number of species)^2

Reimplemented from Transport.

Definition at line 554 of file LiquidTransport.cpp.

References LiquidTransport::m_bdiff, LiquidTransport::m_diff_temp_ok, Transport::m_nsp, LiquidTransport::update_T(), and LiquidTransport::updateDiff_T().

void getMixDiffCoeffs ( doublereal *const d )

virtual

Get the Mixture diffusion coefficients.

The mixture diffusion coefficients are not well defined in the context of LiquidTransport because the Stefan Maxwell equation is solved. Here the mixture diffusion coefficients are defined according to Ficks law:

\[ X_i \vec{V_i} = -D_i \nabla X_i. \]

Solving Ficks Law for \( D_i \) gives a mixture diffusion coefficient

\[ D_i = - X_i \vec{V_i} / ( \nabla X_i ). \]

If \( \nabla X_i = 0 \) this is undefined and the nonsensical value -1 is returned.

Note that this evaluation of \( \vec{V_i} \) requires a solve of the Stefan Maxwell equation making this determination of the mixture averaged diffusion coefficients a slow method for obtaining diffusion coefficients.

Also note that the Stefan Maxwell solve will be based upon the thermodynamic state (including gradients) most recently set. Gradients can be set specifically using set_Grad_V, set_Grad_X and set_Grad_T or through calls to getSpeciesFluxes, getSpeciesFluxesES, getSpeciesVdiff, getSpeciesVdiffES, etc.

Parameters

d	vector of mixture diffusion coefficients units = m2 s-1. length = number of species

void getMobilities ( doublereal *const mobil_e )

virtual

Get the Electrical mobilities (m^2/V/s).

The electrical mobilities are not well defined in the context of LiquidTransport because the Stefan Maxwell equation is solved. Here the electrical mobilities are calculated from the mixture-averaged diffusion coefficients through a call to getMixDiffCoeffs() using the Einstein relation

\[ \mu^e_k = \frac{F D_k}{R T} \]

Note that this call to getMixDiffCoeffs() requires a solve of the Stefan Maxwell equation making this determination of the mixture averaged diffusion coefficients a slow method for obtaining diffusion coefficients.

Also note that the Stefan Maxwell solve will be based upon the thermodynamic state (including gradients) most recently set. Gradients can be set specifically using set_Grad_V, set_Grad_X and set_Grad_T or through calls to getSpeciesFluxes, getSpeciesFluxesES, getSpeciesVdiff, getSpeciesVdiffES, etc.

Parameters

mobil_e Returns the electrical mobilities of the species in array mobil_e. The array must be dimensioned at least as large as the number of species.

doublereal getElectricConduct ( )

virtual

Compute the mixture electrical conductivity from the Stefan-Maxwell equation.

To compute the mixture electrical conductance, the Stefan Maxwell equation is solved for zero species gradients and for unit potential gradient, \( \nabla V \). The species fluxes are converted to current by summing over the charge-weighted fluxes according to

\[ \vec{i} = \sum_{i} z_i F \rho \vec{V_i} / W_i \]

where \( z_i \) is the charge on species i, \( F \) is Faradays constant, \( \rho \) is the density, \( W_i \) is the molecular mass of species i. The conductance, \( \kappa \) is obtained from

\[ \kappa = \vec{i} / \nabla V. \]

Updates the internal value of the gradient of the logarithm of the activity, which is used in the gradient of the chemical potential.

Evaluate the gradients of the activity as they alter the diffusion coefficient.

The gradient of the chemical potential can be written in terms of gradient of the logarithm of the mole fraction times a correction associated with the gradient of the activity coefficient relative to that of the mole fraction. Specifically, the gradients of the logarithms of each are involved according to the formula

\[ \nabla \mu_k = RT \left[ \nabla ( \ln X_k ) + \nabla ( \ln \gamma_k ) \right] = RT \left[ \nabla ( \ln a_k ) \right] \]

The gradient in the activity coefficient requires the use of thermophase getdlnActCoeff that calculates its change based on a chane in the state (i.e. temperature and composition of each species) which was first implemented in MargulesVPSSTP.cpp (LiquidTransport.h doxygen)

(NOT USED IN LiquidTransport.) Diffusion coefficient model for each species expressed as an appropriate subclass of LTPspecies

These subclasses of LTPspecies evaluate the species-specific transport properties according to the parameters parsed in TransportFactory::getLiquidSpeciesTransportData().

Since the LiquidTransport class uses the Stefan-Maxwell equation to describe species diffusivity, the species-specific diffusivity is irrelevant.
