FluidPropertiesInterrogator
User object for querying a single-phase or two-phase fluid properties object
Introduction
The FluidPropertiesInterrogator user object is used to query fluid properties objects that derive from the following types:
SinglePhaseFluidPropertiesVaporMixtureFluidPropertiesTwoPhaseFluidProperties(note thatTwoPhaseNCGFluidPropertiesderives from this)
The user specifies a thermodynamic state at which to evaluate a number of fluid properties. This can be useful for a number of different tasks, such as the following:
Determining values for initial conditions or problem setup
Verifying out-of-bounds inputs to fluid properties interfaces
Getting values to be used in tests
Usage
The interrogator is used with a syntax for AddFluidPropertiesInterrogatorAction. In an input file, the user will only need a block for the FluidPropertiesInterrogator and a block for creating the fluid properties object that will be interrogated. For convenience, an input file to use the interrogator is provided in the module:
# The parameters in this block are used to specify the thermodynamic state
# at which to query the fluid properties package
[FluidPropertiesInterrogator]
fp = fp
p = 1e5
T = 300
vel = 10
[]
# The fluid properties (equation of state) to query is defined here

Let the set of single-phase fluid properties be defined as The set of the same quantities for the stagnation state, rather than the static state, is denoted as .
Let the set of valid inputs for single-phase static fluid properties be and the set of valid inputs for single-phase stagnation fluid properties be For single-phase vapor mixture fluid properties, the valid input sets are as follows:
The following table summarizes the valid input combinations for single-phase fluid properties objects. Note that TwoPhaseNCGFluidProperties inherits from TwoPhaseFluidProperties, so the column TwoPhaseFluidProperties is used to describe fluid properties classes that derive from TwoPhaseFluidProperties but not TwoPhaseNCGFluidProperties.
