TEP Lib thermodynamic properties server

TEP Lib is the library for calculating thermodynamic properties of the Laboratory of Thermodynamics of phase equilibria of the Ecole des Mines de Paris (Mines ParisTech).

Essentially, this is the Java translation by R. Gicquel and B. Liu of TEP Thermosoft libraries initially developed in Delphi. We express our gratitude to EDF, which funded part of this translation, for allowing us to distribute theses libraries.

Coupled to Thermoptim 2.5, it can calculate the properties of mixtures of real fluids, which the software cannot do itself.

Install TEP Lib

To install TEP Lib, download the archive below and unzip it and follow these instructions:

• replace your extUser2.zip file with that of the archive if you do not use special external classes;
• otherwise, load in your extUser2.zip file the external class TEPlib.class included in the extUser2.zip file from the archive, while respecting the internal structure of the archive;
• place the bibTEP.jar library in the installation directory of Thermoptim;place in the mixtures directory the TEPlib.mix file and the folder TEPlib_MEL, which contain the list of systems considered and the data files that define them.

You can then start using these systems to create fluid mixtures.

Documentation of use

You will find below a link to the documentation for using this library, including how to define the data files of external substances.

As stated in the documentation, the equation corresponding to the ideal gas Cp can be given in two forms. The spreadsheet below will convert the values of the DIPPR equation to polynomial values that can be integrated formally.

Finally, it is possible to create simplified (T, s) and (h, P) mixture charts using external class CreateMixtureCharts.
