Article Preview

The viscosity of some simple fluids in the wide density and temperature ranges have been calculated by the modified Enskog theory (MET) and with the help of Kaplun equations. The thermal pressure, second virial coefficient and internal energy are calculated from the modified SAFT-BACK EOS. The proposed scheme was further examined for the prediction of the viscosity of some dense fluids, including Ar, N2, O2, CO2, CH4, C2H6, C3H8 and C4H10. A comparison of the calculated and experimental values of the viscosity yields an overall average deviation of 2.16%.
