چکیده انگلیسی
In our previous works, we applied the integral equations method to calculate transport properties of nonpolar fluids such as Lennard-Jones (12-6) fluid [R. Khordad, Physica A 387 (2008) 4519, M.M. Papari, R. Khordad, Z. Akbari, Physica A 388 (2009) 585]. The present work is a continuation of our studies on transport properties of polar fluids. We use the Stockmayer potential and examine theoretically the viscosity and pressure of several refrigerant mixtures such as R125 + R143a, HFC-125 + HFC-134a, HFC-125 + HFC-32, and HFC-134a + HFC-32. We solve numerically the Ornstein-Zernike (OZ) equation using the hypernetted-chain approximation (HNC) for binary fluid mixtures and obtain the pair correlation functions. Finally, the density and temperature dependence of shear viscosity and pressure are studied using Vesovic-Wakeham method and compared with experimental results. According to the results obtained from the present work reveals that the integral equations method is suitable for predicting the pressure and shear viscosity of this class of fluids.
