ABSTRACT
This
paper reviews the statistical thermodynamic models used for the
prediction and correlation of viscosity for pure component liquids and
multi component liquid systems. The models reviewed were chosen
because they are well known, applied and accepted or appear
potentially promising. Recently developed viscosity model and Flory's
statistical theory has been applied for the prediction of viscosity of
there ternary liquid systems containing n-Alkanes, which are suited
for practical engineering use. Newly developed viscosity model, which
is based on statistical thermodynamics, local compositions and
Eyring's absolute rate theory, gives better results in comparison to
Flory's statistical theory. The applicability and average deviations
for these two methods have been discussed, with the recommended
methods identified.
