NIST' RefProp

NIST Reference Fluid Thermodynamic and Transport Properties Database "REFPROP is a Program, not a Database Containing Measurements. The REFPROP "database" is actually a program and does not contain any experimental information, aside from the critical and triple points of the pure fluids. [from the FAQ:] The program uses equations for the thermodynamic and transport properties to calculate the state points of the fluid or mixture. These equations are the most accurate equations available world wide. A link to one of these equations for R-125 is given below. Their high accuracy is obtained through many coefficients in the equations, and thus the calculation speed will be slower than other equations such as the Peng-Robinson cubic equations. The equations are generally valid over the entire vapor and liquid regions of the fluid, including supercritical states; the upper temperature limit is usually near the point of decomposition of the fluid, and the upper pressure (or density) limit is defined by the melting line of the substance." @ univie / Arnold Neumaier

PE 2000

A Powerful Tool to Correlate Phase Equilibria (by Oliver Pfohl, Stanimir Petkov, and Gerd Brunner) "PE offers subroutines to determine EOS pure-component parameters based on pure-component vapor pressures and densities at saturation conditions. Graphical output routines allow a visual comparison of experimental and calculated data of the vapor pressure curve and PvT data. A useful feature when correlating phase equilibria related to gas-extraction processes is the possibility to enforce pure-component EOS parameters that reproduce the critical temperature and pressure of the supercritical solvent during the pure-component EOS parameter optimization. PE offers subroutines to determine optimum binary interaction parameters for all EOS in order to reproduce the phase behavior of binary and ternary systems with a given set of EOS and mixing rule, best. Further, PE offers the possibility to calculate phase equilibria and densities with given interaction parameters at any conditions. Graphical output routines provide plots of the miscibility gaps in binary and ternary systems in a quality suitable for publications."

Edward Blurock' Thermodynamics

see associated publication

JTHERGAS (a JAVA implementation of THERGAS) estimates thermodynamic information from two dimensional graphical representations of molecules and radicals based on the Benson additivity method. The main use of this method is within automatic combustion mechanism generation systems where fast estimation of a large number and variety of chemical species is needed. The implementation strategy is based on meta-atom definitions and substructure analysis allowing a highly extensible database without modification of the core algorithms. Several interfaces for the database and the calculations are provided from terminal line commands, to graphical interfaces to web-services. The first order estimation of thermodynamics is based summing up the contributions of each heavy atom bonding description. Second order corrections due to steric hindrance and ring strain are made. Automatic estimate of contributions due to internal, external and optical symmetries are also made. Radicals are calculated by taking the difference due to the lost of hydrogen radicals taking into account changes in symmetry, spin, rotations, vibrations and steric hindrances. The software is public domain.The project is still under development, but a development version is visible on the following link. Login as ‘Guest’ (just press the guest button). Click through the ‘Thermodynamic Queries(upper left hand box) and again ‘Thermodynamic Queries’ (again upper left hand box) This brings you to the menu for entering a Nancy Linear Form (similar toSMILES) to calculate the thermodynamic quantities.

"Hydra is a high level, declarative language for modelling and simulation of physical systems. Systems in Hydra are being modelled using implicitly formulated (undirected) Differential Algebraic Equations (DAEs). While, physical modelling is our main focus any domain is fine where problems can be formulated using DAEs."

modelyze

Modelyze (MODEl and anaLYZE) is a host language designed for modeling and analysis of cyber-physical systems (CPS). Modelyze is not a modeling language itself, but a host language where domain-specific languages (DSLs) can be embedded. It has been tested and evaluated on equation-based object-oriented DSLs, used for modeling of physical systems.

DUMUx

DuMux, DUNE for Multi-{Phase, Component, Scale, Physics, ...} flow and transport in porous media

This is a free and open-source simulator for flow and transport processes in porous media. It is based on the Distributed and Unified Numerics Environment DUNE. Its main intention is to provide a sustainable and consistent framework for the implementation and application of porous media model concepts and constitutive relations. It has been successfully applied to CO2 storage scenarios, environmental remediation problems, transport of therapeutic agents through biological tissue, and subsurface-atmosphere coupling. The development of DuMux started in January 2007 at the University of Stuttgart.

IAPWSPy is a python package that allows to manipulate thermophysical properties of water, thanks to the IAPWS-95 (International Association for the Properties of Water and Steam) experimental correlations. All correlations are currently based on the saturated properties of water and package allow to draw some usual thermodynamical diagrams (Mollier, Clapeyron,...).

It calculates thermodynamic properties and the conomic feasibility of such a plant, based on assumptions made in class. It also yields three plots: T-s (Entropy vs. Temperature), P-v (Specific Volume vs. Pressure), and P-h (Enthalpy vs. Pressure) diagrams for the various states of the water control volume within the power plant cycle. The script 'jhyates_fdpfunction' has similar functionality in that it calculates the thermodynamic properties of the given power plant cycle, but is meant to see the sensitivity of those properties to varying inputs. It's much more rough; you have to get in there and modify the input variables and the ranges over which they can vary in value manually. However, it did its job for the assignment. The script produces plots of heat transfer in and out of the cycle, work into the cycle, and the thermal efficiency and backwork ratio of the cycle. A set of these plots for the current set of inputs, for the interested, is located at http://imgur.com/a/HmfQd." CoolProp "samplecode; python;" opensource process
