Comparaison entre la viscosité des gaz rares denses et la viscosité de modèles statistiques

The values of the shear viscosity of simple dense gases at room temperature up to 6000 bar, measured by the authors, have been compared to values calculated with statistical models: Lennard-Jones, Van-der-Waals and hard sphere dense fluids. The values from molecular dynamic modeling of Couette flow, for a Lennard-Jones system, along temperature) are in agreement with the experimental values of shear viscosity of helium and neon.With the hard sphere model the difference between the values calculated from the Kubo relation with the equilibrium molecular-dynamic calculations and experimental values for the noble gases has not the same representation according as the gas is at high or low reduced temperature. For this model some corrections have been calculated.
