![]() ![]() #Nist refprop program codeThese results include: Equilibrium properties: density, compressibility factor, enthalpy, entropy, Cp, Cp/Cv, sound speed, Joule-Thomson coefficient Transport properties: viscosity, thermal conductivity Features: bubble and dew point pressure calculations bubble and dew point temperature calculations flash calculations () saturation properties for pure components tables of thermophysical properties with user selected dependent and independent variables ability to add new fluids using minimal data (user must supply at least Tc, Pc, Vc, MW and boiling point) ability to estimate properties of petroleum fractions characterized by an average normal boiling point and an API gravity choice of units FORTRAN source code for property calculations NOTE: Many of the fluids contained in SUPERTRAPP are also available in the REFPROP database. SUPERTRAPP performs phase equilibria calculations and gives the thermophysical properties of all phases and the feed. #Nist refprop program softwareThe REFPROP software and related files DO NOT COME WITH NPSS the user must contact NIST to purchase his/her own. ![]() #Nist refprop program freeBut the free version of that software dose not work appropriately. The NIST REFPROP software program is a powerful tool for calculating thermophysical properties of industrially important fluids, and this manuscript describes the models implemented in, and features of, this software. mix extension, in the mixtures directory). The components are selected from a database of 210 components, mostly hydrocarbons. I know that Refprop software can provide properties of the material. Over 100 high-accuracy EOS for pure compounds are collected in NIST REFPROP software 71 and are also available through TDE. Therefore, the objective of the current paper is to check if these deficiencies have been fixed, because in nuclear engineering as well as other areas only a conservative approach can be used, i.e., all peak values should be the minimum possible ones.SUPERTRAPP is an interactive computer program for predicting thermodynamic and transport properties of pure fluids and fluid mixtures containing up to 20 components. In the previous version(s) of the NIST REFPROP 9.1 and higher, three basic thermophysical properties such as specific heat, thermal conductivity, and volumetric expansivity have infinite peak values in the critical point, which was a theoretical approach. The most complicated properties calculations are in the critical point, where all thermophysical properties are subjected to very significant variations, i.e., almost vertical drops or rises or have peaking functions. This version includes 147 pure fluids, 5 pseudo-pure fluids (e.g., air, etc.), and mixtures with up to 20 components. Just two years ago, i.e., in 2018, the latest version was released – Ver. Time from time this program is updated with new fluids, or/and a wider range of pressures and temperatures, or/and with improved equations/correlations. CoolProp: This section includes information about the CoolProp software, listings of inputs, etc. For tens of years, the NIST REFPROP program is used for these calculations, which can be possibly considered as the best one in the world. McLinden, NIST Physical and Chemical Properties Division (C) 2010 by the U.S. The software installer includes 7 files and is. REFPROP is NISTs Standard Reference Database by E.W. The main program executable is REFPROP.EXE. Any heat transfer or thermodynamics calculations as well as many other calculations require a solid knowledge of various physical/thermophysical/thermodynamics properties of various fluids (liquids, vapours, and gases) within a wide range of pressures and temperatures from lower ones and up to critical and supercritical ones. It adds an extension to the users Internet Explorer web browser. ![]()
