ABSTRACT:

Using perturbation theory for the molecular fluid to determine the effective hard sphere diameter and obtain expression for radial distribution function (RDF) of the hard sphere (HS) fluid. Shear viscosity of the molecular fluid are expressed in terms of the HS fluid of properly chosen hard sphere diameter. The shear viscosity μs of a dense HS fluid are obtained by the Revised Enskog theory (RET). Theory is applied to calculate shear μs of fluid N2. The theory provides good results at low density limit.
