FluidProperties System

Overview

FluidProperties objects define interfaces for computing thermodynamic properties of fluids (liquids and gases).

Interfaces

Because two independent, intensive thermodynamic properties define a thermodynamic state, most interfaces in these objects are of the form $f(a,b)$ where $f$ is the desired thermodynamic property and $a$ and $b$ are independent, intensive thermodynamic properties that define the thermodynamic state. The corresponding function name is f_from_a_b. See the following table for the list of thermodynamic properties and their corresponding names in the interfaces:

Name	Symbol	Description
`beta`	$\beta$	Volumetric expansion coefficient
`c`	$c$	Speed of sound
`cp`	$c_p$	Isobaric specific heat capacity
`cv`	$c_v$	Isochoric specific heat capacity
`e`	$e$	Specific internal energy
`g`	$g$	Gibbs free energy
`gamma`	$\gamma=\frac{c_p}{c_v}$	Ratio of specific heats
`h`	$h$	Specific enthalpy
`k`	$k$	Thermal conductivity
`mu`	$\mu$	Dynamic viscosity
`p`	$p$	Pressure
`rho`	$\rho$	Density
`s`	$s$	Specific entropy
`T`	$T$	Temperature
`v`	$v$	Specific volume
