Abstract
The Davis-Rice-Sengers square-well theory of transport for simple dense gases and liquids is tested with Yvon-Born-Green theoretical pair correlation functions for σ2/σ1=1.85. Comparison with experiment shows that the theory correctly predicts the qualitative features of liquid argon transport properties and quantitatively is very good at high temperatures and densities in the liquid region. An adjustment of intermolecular potential parameters is shown to improve the predictions of the theory uniformly. Some comments are made concerning the success of this theory in light of recent studies of the Rice-Allnatt theory.
