## Detailed Description

Transport Parameters for pure water.

Definition at line 19 of file WaterTransport.h.

## 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.

Definition at line 35 of file WaterTransport.cpp.

References WaterTransport::init(), and Transport::thermo().

## Member Function Documentation

## ◆ transportType()

virtual std::string transportType | ( |  | ) | const
| inline virtual

Identifies the Transport object type.

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

Reimplemented from Transport.

Definition at line 31 of file WaterTransport.h.

## ◆ viscosity()

double viscosity | ( |  | ) |
| virtual

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 the paper: J. V. Sengers, J. T. R. Watson, "Improved International Formulations for the Viscosity and Thermal Conductivity of Water Substance", J. Phys. Chem. Ref. Data, 15, 1291 (1986).

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 48 of file WaterTransport.cpp.

References Phase::density(), Transport::m_thermo, and Phase::temperature().

## ◆ bulkViscosity()

virtual doublereal bulkViscosity | ( |  | ) |
| inline virtual

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 | ( |  | ) |
| virtual

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 the paper: J. V. Sengers, J. T. R. Watson, "Improved International Formulations for the Viscosity and Thermal Conductivity of Water Substance", J. Phys. Chem. Ref. Data, 15, 1291 (1986).

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 96 of file WaterTransport.cpp.

References Phase::density(), Transport::m_thermo, and Phase::temperature().

## ◆ init()

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

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
