Study of frequency dispersion of shear and bulk viscosity coefficients for liquid argon, krypton and xenon under different parameters of state

Using the obtained kinetic equations for one-particle f1x→1,t and two-particle f2x→1,x→2,t distribution functions the frequency dispersion of shear ηS(ω) and bulk ηV(ω) viscosity coefficients of simple liquids are studied. The numerical calculations of the coefficients ηS(ω) and ηV(ω) for liquid Ar, Kr, Xe have been performed for definite potential of intermolecular interaction Φr→ and radial distribution function gr→ in broad temperature T, density ρ, and frequency ω ranges. The obtained results of theoretical calculations of viscosity coefficients of these liquids are in good agreements with the existed experimental data.
