Parameters
----------
name
A String specifying the interaction property repository key.
dataTable
A sequence of sequences of Floats specifying the viscous and hydrodynamic resistance
coefficients when *definition*=BULK_VISCOSITY. Each sequence contains the following
data:
- The viscous resistance coefficient.
- The hydrodynamic resistance coefficient.
- The average absolute pressure, if the data depend on pressure.
- The average temperature, if the data depend on temperature.
- The value of the first field variable, if the data depend on field variables.
- The value of the second field variable.
- Etc.
Alternatively, the sequence data may specify the mass flow rate. This is applicable only
when *definition*=MASS_FLUX. In this form, only one sequence is specified and that
sequence contains the following data:
- The mass flow rate per unit area.
Alternatively, the sequence data may specify the mass rate leakage. This is applicable
only when *definition*=MASS_RATE_LEAK. Each sequence contains the following data:
- The absolute value of the mass flow rate per unit area. (The first tabular value
entered must always be zero.)
- The absolute value of the pressure difference. (The first tabular value entered must
always be zero.)
- The average absolute pressure, if the data depend on pressure.
- The average temperature, if the data depend on temperature.
- The value of the first field variable, if the data depend on field variables.
- The value of the second field variable.
- Etc.
Alternatively, the sequence data may specify the volume flow rate. This is applicable
only when *definition*=VOL_FLUX. In this form, only one sequence is specified and that
sequence contains the following data:
- The volumetric flow rate per unit area.
Alternatively, the sequence data may specify the volume rate leakage. This is applicable
only when *definition*=VOL_RATE_LEAK. Each sequence contains the following data:
- The absolute value of the volumetric flow rate per unit area. (The first tabular value
entered must always be zero.)
- The absolute value of the pressure difference. (The first tabular value entered must
always be zero.)
- The average absolute pressure, if the data depend on pressure.
- The average temperature, if the data depend on temperature.
- The value of the first field variable, if the data depend on field variables.
- The value of the second field variable.
- Etc.
definition
A SymbolicConstant specifying the type of fluid exchange property to be defined.
Possible values are BULK_VISCOSITY, MASS_FLUX, MASS_RATE_LEAK, VOL_FLUX, and
VOL_RATE_LEAK. The default value is BULK_VISCOSITY.
pressureDependency
A Boolean specifying whether the data will have pressure dependency. This argument is
applicable only when *definition*=BULK_VISCOSITY, or when *definition*=MASS_RATE_LEAK,
or when *definition*=VOL_RATE_LEAK. The default value is OFF.
temperatureDependency
A Boolean specifying whether the data will have temperature dependency. This argument is
applicable only when *definition*=BULK_VISCOSITY, or when *definition*=MASS_RATE_LEAK,
or when *definition*=VOL_RATE_LEAK. The default value is OFF.
fieldDependencies
An Int specifying the number of field variable dependencies in the data. This argument
is applicable only when *definition*=BULK_VISCOSITY, or when
*definition*=MASS_RATE_LEAK, or when *definition*=VOL_RATE_LEAK. The default value is 0.
Returns
-------
A FluidExchangeProperty object.
