Viscosity calculation of dense fluids using modified Enskog theory (MET) and LIR equation of state

Liquid viscosity is one of the most significant transport properties required by chemical engineers involved in reactor applications and heat and mass transfers. Accurate experimental measurements of viscosity are a complex task. Therefore, in this situation, any generalized prediction approach is highly desirable for practical engineering uses. The viscosity models found in literature range from highly theoretical to simple empirical correlations [1]. Nevertheless,because of the complexity of the intermolecular forces in dense fluids, makes even a semi-theoretical model extremely difficult. In this work, a new method based on the modified Enskog theory is presented for calculation of viscosity at high densities (ρ > ρc).
