Modification of Tao-Mason equation of state: Application to refrigerant fluids / Mohammad Mehdi Papari in International journal of refrigeration, Vol. 34 N° 1 (Janvier 2011) 

Public ISBD [article]  in International journal of refrigeration > Vol. 34 N° 1 (Janvier 2011) . - pp. 268-274 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.
