โฆ Synopsis
The cwefticienr of viscosity fw a square-Nell fluid is calculated by mokcuhr dynamics as a function of the well-depth for dcnsitio up to the rqion of the ffuid-solid phase trawition. The inclusion of nn attractke contnbution in the inter-moIecuhr porcntizl has ;1 profound inftuence on the behaviour of the viscosity coefficient and is also responsible for the qualitative correspondence with reaI s>,tems uhich has been found for densities above the critical one_

E&eived 9 Dek-nber 1974. Shear viscosity is calculated for a dense flnid of square-well rough spheres. The results are campared with czkulated shear viscosities for the familiar hard-sphere, square-well and rough-sphere models.
Systematic investigations of the viscosity coefficient of gases have been performed in the subcritical density region, using molecular dynamics. The model systems consisted of Lennard-Jones particles and of particles with a variant of the Lennard-Jones intermolecular potential. A comparison is made
