1 About
The extension makes water properties based on the IAPWS-IF97 (doi: 10.1115/1.483186) definition available for OpenFOAM (R) solvers of the compressible buoyant* family, such as buoyantPimpleFoam. The extension is based on the work for the real gas branch of openfoam-ext-1.6. The water properties come from the C-library freesteam.
2 Installation
2.1 Prerequisited
- Full installation of OpenFOAM >=2.2 from http://www.openfoam.org
- Installed freesteam >=2.0 from http://freesteam.sourceforge.net/
2.2 Installing IAPWS-IF97-OF
Open a command line window and navigate to directory you would like to store the source code for IAPWS-IF97-OF. Then run the following commands in a command line on your computer
# git clone https://github.com/romansCode/IAPWS-IF97-OF.git
# cd IAPWS-IF97-OF
# wclean && wmake libso
3 Usage
- add libIAPWSRangeThermo.so and libfreesteam.so to the libraries in controlDict
libs { "libIAPWSRangeThermo.so" "libfreesteam.so" }
- In the the thermophysicalProperties file, which can also be found in the example folder in the source code use the following.
thermoType { type heRhoThermo; // Thermophysical model based on sensible enthalpy mixture pureMixture; // Only water transport IAPWSTransport; // (mu, k) thermo hIAPWS; // (Cp) equationOfState eosIAPWS; // (rho) specie specie; energy sensibleEnthalpy; } // outside the pressure and temperature range, the properties will be capped to // the min and max values at the range limits mixture { IAPWSProperties { pMax 300e5; // max allowed pressure pMin 221e5; // min allowed pressure } specie { nMoles 1; molWeight 18; // Water } }
- The pressure limits can be used to stabilise the computations at startup, however, they are not necessary and can be set to the limits of the properties table (for 0°C < T < 800°C p<100 MPa and for 800°C < T < 2000 °C p < 10 MPa).
