MOLECULAR DYNAMICAL CALCULATIONS ON THE VISCOSITY OF A SQUARE-WELL FLUID

The coefficient of viscosity for a square-well fluid is calculated by molecular dynamics as a function of the well-depth for densities up to the region of the fluid-solid phase transition. The inclusion of an attractive contribution in the intermolecular potential has a profound influence on the behaviour of the viscosity coeffient and is also responsible for the qualitative correspondence with real systems which has been found for densities above the critical one. © 1979.
