default constructor

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 25 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 38 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.

◆ 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.

◆ 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
thermoPointer to the ThermoPhase object
modeChemkin compatible mode or not. This alters the specification of the collision integrals. defaults to no.
log_levelDefaults to zero, no logging
