Water97FluidProperties
Fluid properties for water and steam (H2O) using IAPWS-IF97
The water implementation in Fluid Properties is the IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam. This formulation calculates properties of water and steam using pressure and temperature as inputs. The IAPWS-IF97 formulation is split into five different regions in the phase diagram.
All five regions are implemented in the Fluid Properties module. To avoid iteration in region 3 of the IAPWS-IF97 formulation, the backwards equations from IAPWS (2014) are implemented.
Viscosity is calculated using the IAPWS 2008 formulation (IAPWS, 2008). Note that the critical enhancement has not been implemented.
Thermal conductivity is calculated using the IAPS 1985 formulation (IAPS, 1985). Although there is a newer formulation available (IAPWS, 2011), it is significantly more complicated, so has not been implemented yet.
Dissolution of a dilute gas into water is calculated using Henry's law (IAPWS, 2004).

# FluidFlower International Benchmark study model
# CSIRO 2023
#
# This example can be used to reproduce the results presented by the
# CSIRO team as part of this benchmark study. See
# Green, C., Jackson, S.J., Gunning, J., Wilkins, A. and Ennis-King, J.,
# 2023. Modelling the FluidFlower: Insights from Characterisation and
# Numerical Predictions. Transport in Porous Media.
#
# This example takes a long time to run! The large density contrast
# between the gas phase CO2 and the water makes convergence very hard,
# so small timesteps must be taken during injection.
#
# This example uses a simplified mesh in order to be run during the
# automated testing. To reproduce the results of the benchmark study,
# replace the simple layered input mesh with the one located in the
# large_media submodule.
#
# The mesh file contains:
# - porosity as given by FluidFlower description
# - permeability as given by FluidFlower description
# - subdomain ids for each sand type
#
# The nominal thickness of the FluidFlower tank is 19mm. To keep masses consistent
# with the experiment, porosity and permeability are multiplied by the thickness
thickness = 0.019

# Following Benchmark Specifications and Data Requirements for the AREVA heated-bundle test in its Fuel Cooling Test Facility (FCTF)
# as part of a U.S. DOE funded project: Towards a Longer-Life Core. In partnership with TerraPower, TAMU and ANL,
# AREVA NP tested a wire-wrapped pin bundle. The bundle consists of electrically heated pins and non-heated pins.
# This test collected measurements to evaluate thermal hydraulic performance of a wire wrapped bundle, useful for CFD and other software validation.
