Detailed Description

Class for single-component water.

This is designed to cover just the liquid and supercritical phases of water.

The reference is W. Wagner, A. Pruss, "The IAPWS Formulation 1995 for the Thermodynamic Properties of Ordinary Water Substance for General and Scientific Use," J. Phys. Chem. Ref. Dat, 31, 387, 2002.

Specification of Species Standard State Properties

The offsets used in the steam tables are different than NIST's. They assume u_liq(TP) = 0.0, s_liq(TP) = 0.0, where TP is the triple point conditions:

 -  u(273.16, rho)    = 0.0
 -  s(273.16, rho)    = 0.0
 -  psat(273.16)      = 611.655 Pascal
 -  rho(273.16, psat) = 999.793 kg m-3

These "steam table" assumptions are used by the WaterPropsIAPWS class. Therefore, offsets must be calculated to make the thermodynamic properties calculated within this class to be consistent with thermo properties within Cantera.

The thermodynamic base state for water is set to the NIST basis here by specifying constants, EW_Offset and SW_Offset, one for energy quantities and one for entropy quantities. The offsets are specified so that the following properties hold:

Delta_Hfo_idealgas(298.15) = -241.826 kJ/gmol
So_idealgas(298.15, 1bar) = 188.835 J/gmolK

(From http://webbook.nist.gov)

The "o" here refers to a hypothetical ideal gas state. The way we achieve this in practice is to evaluate at a very low pressure and then use the theoretical ideal gas results to scale up to higher pressures:

Ho(1bar) = H(P0)

So(1bar) = S(P0) + RT ln(1bar/P0)

%Application within Kinetics Managers

This is unimplemented.

XML Example

Note: The XML input format is deprecated and will be removed in Cantera 3.0

An example of an XML Element named phase setting up a WaterSSTP object with id "water" is given below.

<!-- phase water     -->
<phase dim="3" id="water">
  <elementArray datasrc="elements.xml">O  H </elementArray>
  <speciesArray datasrc="#species_data">H2O</speciesArray>
  <state>
    <temperature units="K">300.0</temperature>
    <pressure units="Pa">101325.0</pressure>
  </state>
  <thermo model="PureLiquidWater"/>
  <kinetics model="none"/>
</phase>

Note the model "PureLiquidWater" indicates the usage of the WaterSSTP object.

Member Function Documentation

◆ type()

virtual std::string type ( ) const

inlinevirtual

String indicating the thermodynamic model implemented.

Usually corresponds to the name of the derived class, less any suffixes such as "Phase", TP", "VPSS", etc.

Reimplemented from SingleSpeciesTP.

Definition at line 112 of file WaterSSTP.h.

◆ phaseOfMatter()

std::string phaseOfMatter ( ) const

virtual

String indicating the mechanical phase of the matter in this Phase.

Options for the string are:

unspecified
supercritical
gas
liquid
solid
solid-liquid-mix
solid-gas-mix
liquid-gas-mix
solid-liquid-gas-mix

unspecified is the default and should be used when the Phase does not distinguish between mechanical phases or does not have enough information to determine which mechanical phase(s) are present.

Todo:: Needs to be implemented for all phase types. Currently only implemented for PureFluidPhase.

Reimplemented from ThermoPhase.

Definition at line 38 of file WaterSSTP.cpp.

References WaterSSTP::m_sub, and WaterPropsIAPWS::phaseState().

◆ cv_mole()

doublereal cv_mole ( ) const

virtual

Molar heat capacity at constant volume. Units: J/kmol/K.

Reimplemented from SingleSpeciesTP.

Definition at line 147 of file WaterSSTP.cpp.

References WaterPropsIAPWS::cv(), and WaterSSTP::m_sub.

◆ pressure()

doublereal pressure ( ) const

virtual

Return the thermodynamic pressure (Pa).

This method must be overloaded in derived classes. Within Cantera, the independent variable is either density or pressure. If the state is defined by temperature, density, and mass fractions, this method should use these values to implement the mechanical equation of state \( P(T, \rho, Y_1, \dots, Y_K) \). Alternatively, it returns a stored value.

◆ setPressure()

void setPressure ( doublereal p )

virtual

Set the internally stored pressure (Pa) at constant temperature and composition.

Therefore, this function may either solve for the density that will yield the desired input pressure or set an independent variable. The temperature and composition are held constant during this process.

p	input Pressure (Pa)

◆ initThermo()

void initThermo ( )

virtual

Initialize the ThermoPhase object after all species have been set up.

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. Derived classes which do override this function should call their parent class's implementation of this function as their last action.

When importing a CTML phase description, this method is called from initThermoXML(), which is called from importPhase(), just prior to returning from function importPhase().

When importing from an AnyMap phase description (or from a YAML file), this method is responsible for setting model parameters from the data stored in m_input.

Set equation of state parameter values from XML entries.

This method is called by function importPhase() when processing a phase definition in an input file.

Note, this method is called before the phase is initialized with elements and/or species.

Parameters

This class is used to house several approximation routines for properties of water. This object owns m_waterProps, and the WaterPropsIAPWS object used by WaterProps is m_sub, which is defined above.

◆ m_mw

doublereal m_mw

private

Molecular weight of Water -> Cantera assumption.

◆ EW_Offset

doublereal EW_Offset

private

Offset constants used to obtain consistency with the NIST database.

This is added to all internal energy and enthalpy results. units = J kmol-1.

◆ SW_Offset

doublereal SW_Offset

private

Offset constant used to obtain consistency with NIST convention.

This is added to all internal entropy results. units = J kmol-1 K-1.

◆ m_ready

bool m_ready

private

Boolean is true if object has been properly initialized for calculation.

◆ m_allowGasPhase

bool m_allowGasPhase

private

Since this phase represents a liquid (or supercritical) phase, it is an error to return a gas-phase answer.

However, if the below is true, then a gas-phase answer is allowed. This is used to check the thermodynamic consistency with ideal-gas thermo functions for example.
