Software for the
calculation of thermophysical properties of fluids
The program calculates thermodynamic and transport properties for a large variety of fluids and fluid mixtures using many modern physical models.
FluidProp is a software library that complies
with the COM
standard therefore it can be seamlessly called by many different programs and
programming environments. Some examples of program that can be easily interfaced
to FluidProp are:
• Microsoft Excel
• Mathworks Matlab/Simulink
• Microsoft Visual Basic
• Intel Visual Fortran
• Compaq Visual Fortran
• Microsoft Visual C++
• Borland C++
An Excel Add-in that makes the use of FluidProp immediate is included in the package together with examples of all the above mentioned clients.
FluidProp is also the core property calculation engine of Cycle-Tempo, a software for the thermodynamic optimization of energy conversion systems.
As it is schematically shown in the picture below, FluidProp is actually a standard interface to several software libraries for the calculation of thermodynamic and transport properties of fluids.
FluidProp has been initially conceived by P. Colonna, the concept has been elaborated, extended and implemented by T.P. van der Stelt. Alberto Guardone has contributed vThermo to FluidProp and participated in the implementation of the RefProp model.
GasMix implements an ideal gas model for fluids and mixtures.
IF97 implements models for the calculation of thermodynamic and transport properties of water and steam according the IAPWS.
RefProp implements reference equations of state as well as technical equations of state for pure fluids and mixtures. Refprop is developed and maintained by the National Institute of Standard and Technologies and any specific information can be found in the original distribution package. FluidProp standardizes the RefProp interface and makes it a COM server. We gratefully recognize the friendly cooperation of Dr. E.W. Lemmon of the Physical and Chemical Properties Division of NIST at Boulder.
StanMix implements a model based on a cubic equation of state and modern mixing rules that can describe a huge variety of fluids and mixtures with few parameters.
TPSI implements accurate thermodynamic
models for few fluids as described in:
Reynolds, W.C., Thermodynamic properties in S.I., Department of Mechanical Engineering - Stanford University, Stanford, CA, 1979.
vThermo implements the ideal gas, ideal Z gas, Van der Waals, Redlich-Kwong, Soave-Redlich-Kwong, Peng-Robinson, Clausius II and the Martin-Hou equations of state for pure fluids. It has been contributed to FluidProp by Alberto Guardone of Dipartimento di Ingegneria Aerospaziale, Politecnico di Milano, Italy.
Notes: RefProp is not distributed together with the standard version of FluidProp because RefProp is owned and distributed by the National Institute of Standards and Technologies (NIST). To get access to RefProp via the common FluidProp interface you must own a valid license of RefProp 8 (or later). Once a valid a license has been obtained or if you have already a valid license, you can contact us about how to establish a link between FluidProp and RefProp. vThermo is also not available in the standard version of FluidProp, becasue it is still in progress. Also for vThermo you can contact us about how to get access to it.
