WebREFPROP is based on the most accurate pure fluid and mixture models currently available. It implements three models for the thermodynamic properties of pure fluids: equations of state explicit in Helmholtz energy, the modified Benedict-Webb-Rubin equation of state, and an extended corresponding states (ECS) model. WebThis program, developed by the National Institute of Standards and Technology (NIST), provides tables and plots of the thermodynamic and transport properties of industrially important fluids and their mixtures with an emphasis on refrigerants and hydrocarbons, especially natural gas systems. REFPROP is based on the most accurate pure fluid and ...
WebThe REFPROP v7.0 Database The NIST real gas model supports 83 pure fluids from the REFPROP database. These include 39 materials that were originally included in REFPROP v7.0 plus the extra materials that were made available in the NIST web site later. WebWhen a mixture has been selected, the fluid information screen will display a window containing the mixture name, molar mass (molecular weight), critical properties, and …
WebThe default pure fluid equations of state in REFPROP are not the same as those used in the GERG model, rather they are more complex with lower uncertainties. The GERG equations for the pure fluids are shorter, less complex, and faster, but slightly less accurate. WebREFPROP program, e.g.R406c. , A complete list of fluid names is provided in the REFPROP and manuals. The fluid system name must be must be enclosed within single quotes. A mixture of pure components is identified by use of a plus (+ sign between the component names, e.g., 'R12+R152a'. Upper and lower case letters are treated identically.
Webacentric factor, and dipole moment of each pure fluid were used in the final scheme. The values of ζ ij range between –106 and +11; a value of zero for ζ ij corresponds to a pseudo ideal mixture. This method is implemented in the NIST REFPROP database for fluids typically used as refrigerants in
