Constructor & Destructor Documentation

◆ WaterTransport()

WaterTransport	(	ThermoPhase *	thermo = `0`,
		int	ndim = `-1`
	)

default constructor

Parameters

thermo	ThermoPhase object that represents the phase. Defaults to zero
ndim	Number of dimensions of the flux expressions. Defaults to a value of one.

Deprecated:: The thermo and ndim parameters will be removed after Cantera 3.0. The ThermoPhase object should be specifed when calling the init method.

Definition at line 33 of file WaterTransport.cpp.

Member Function Documentation

◆ transportModel()

string transportModel ( ) const

inlineoverridevirtual

Identifies the model represented by this Transport object.

Each derived class should override this method to return a meaningful identifier.

Since: New in Cantera 3.0. The name returned by this method corresponds to the canonical name used in the YAML input format.

Reimplemented from Transport.

Definition at line 34 of file WaterTransport.h.

◆ viscosity()

double viscosity ( )

overridevirtual

Returns the viscosity of water at the current conditions (kg/m/s)

This function calculates the value of the viscosity of pure water at the current T and P.

The formulas used are from Sengers and Watson [38].

The formulation is accurate for all temperatures and pressures, for steam and for water, even near the critical point. Pressures above 500 MPa and temperature above 900 C are suspect.

Reimplemented from Transport.

Definition at line 46 of file WaterTransport.cpp.

◆ bulkViscosity()

double bulkViscosity ( )

inlineoverridevirtual

The bulk viscosity in Pa-s.

The bulk viscosity is only non-zero in rare cases. Most transport managers either overload this method to return zero, or do not implement it, in which case an exception is thrown if called.

Reimplemented from Transport.

Definition at line 51 of file WaterTransport.h.

◆ thermalConductivity()

double thermalConductivity ( )

overridevirtual

Returns the thermal conductivity of water at the current conditions (W/m/K)

This function calculates the value of the thermal conductivity of water at the current T and P.

The formulas used are from Sengers and Watson [38].

The formulation is accurate for all temperatures and pressures, for steam and for water, even near the critical point. Pressures above 500 MPa and temperature above 900 C are suspect.

Reimplemented from Transport.

Definition at line 94 of file WaterTransport.cpp.

◆ init()

void init	(	ThermoPhase *	thermo,
		int	mode = `0`,
		int	log_level = `0`
	)

overridevirtual

Initialize a transport manager.

This routine sets up a transport manager. It calculates the collision integrals and populates species-dependent data structures.

Parameters

thermo	Pointer to the ThermoPhase object
mode	Chemkin compatible mode or not. This alters the specification of the collision integrals. defaults to no.
log_level	Defaults to zero, no logging
