Titre : Extension of Tao-Mason equation of state to mixtures : results for PVTx properties of refrigerants fluid mixtures Type de document : texte imprimé Auteurs : Fakhri Yousefi, Auteur ; Jalil Moghadasi, Auteur ; Mohammad Mehdi Papari, Auteur Année de publication : 2009 Article en page(s) : pp. 5079–5084 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Tao-Mason equation of state Refrigerant fluid mixtures Résumé : Tao and Mason ( J. Chem. Phys.1994, 100, 9075−9084) developed a statistical-mechanical-based equation of state (EOS) for pure substances. In the present study, we have successfully extended this EOS to fluid mixtures, selecting refrigerant fluid mixtures as the test systems. The considered refrigerant mixtures are R32 + R125, R32 + R134a, R134a + R152a, R125 + R143a, R125 + R134a, R32 + R227ea, R134a + R290, and R22 + R152a. The second virial coefficient, B(T), necessary for the mixture version of the Tao−Mason (TM) EOS, was determined using a two-parameter corresponding-states correlation obtained from the analysis of the speed of sound data and two constants: the enthalpy of vaporization ΔHvap and the molar density ρnb, both at the normal boiling point. Other temperature-dependent quantities, including the correction factor α(T) and van der Waals covolume b(T), were obtained from the Lennard-Jones (12−6) model potential. The cross parameters B12(T), α12(T), and b12(T), required by the EOS for mixtures, were determined with the help of simple combining rules. The constructed mixture version of the TM EOS was extensively tested by comparison with experimental data. The results show that the molar gas and liquid densities of the refrigerant mixtures of interest can be predicted to within 1.3% and 2.69%, respectively, over the temperature range of 253−440 K and the pressure range of 0.33−158 bar. The present EOS was further assessed through comparisons with the Ihm−Song−Mason (ISM) and Peng−Robinson (PR) equations of state. In the gas phase, the TM EOS outperforms the two other equations of state. In the liquid phase, there is no noticeable difference between the TM EOS and the PR EOS, but both work better than the ISM EOS.

Titre : Modification of Tao-Mason equation of state: Application to refrigerant fluids Titre original : Modification de l'équation d'état Tao-Mason : application aux fluides frigorigènes Type de document : texte imprimé Auteurs : Mohammad Mehdi Papari, Auteur ; Rozita Nejabat, Auteur ; Jalil Moghadasi, Auteur Année de publication : 2011 Article en page(s) : pp. 268-274 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Refrigerant Equation of state Enthalpy Entropy Thermodynamic property Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : The present work addresses a simplified procedure for the calculation of certain parameters in the Tao-Mason (TM) equation of state needed to estimate thermodynamic properties of 12 ozone–friendly refrigerants fluids. The calculations cover wide ranges extending from the dilute vapor or gas to highly compressed liquid and supercritical region. The theoretical equation of state (EOS) is that of Tao and Mason which is based on statistical mechanical perturbation theory. The novelty of the present work is that we use two scaling constants, the enthalpy of vaporization and the molar density, both evaluated at the normal boiling temperature. This approach contrasts with the original procedure that employs five scaling constants including the critical temperature, the critical pressure, the Boyle temperature, the Boyle pressure and the acentric factor for calculating three parameters second virial coefficient and temperature-dependent parameters. The modified TM EOS predicts thermodynamic properties with equal or better accuracy than those emerging from the original TM EOS.
