Viscosity and Thermal Conductivity Models of 151 Common Fluids Based on Residual Entropy Scaling and Cubic Equations of State.

ABSTRACT: A residual entropy scaling (RES) approach combined with the cubic equation of state (EoS) was developed to calculate the viscosity and thermal conductivity of 151 common fluids. These pure fluids are all the pure fluids available in the NIST's REFPROP 10.0 database. Seven cubic EoS were studied, while only four yielded good and similar results; these are Peng-Robinson (PR), Soave-Redlich-Kwong (SRK), Patel-Teja-Valderrama (PTV), and Yang-Frotscher-Richter (YFR) EoS. The parameters of a pure fluid in this cubic EoS + RES approach were fitted using experimental data if they are available in the NIST ThermoData Engine database 10.1, otherwise, using the calculations of REFPROP 10.0. This approach is applicable in the entire temperature and pressure ranges for thermal conductivity and at press
