Аннотация:
It is demonstrated that properly reduced transport coefficients (self-diffusion, shear viscosity, and thermal conductivity) of the Lennard-Jones liquid along isotherms exhibit quasi-universal scaling on the density divided by its value at the freezing point. This finding is rationalized in terms of Rosenfeld’s excess entropy scaling and isomorph theory of Roskilde-simple systems. The observed scaling is closely related to the density scaling of transport coefficients of hard-sphere fluids. It is further demonstrated that the freezing density scaling operates reasonably well for viscosity and thermal conductivity coefficients of liquid argon, krypton, and xenon. Quasi-universality of the reduced transport coefficients at their minima and at freezing conditions is briefly discussed.
