title: Kinetic equation for liquids with a multistep potential of interaction: calculation of transport coefficients
abstract: Using the boundary conditions method, we find normal solutions to a kinetic equation proposed recently by us [Physica A 234, 89 (1996)] to describe nonequilibrium properties of classical liquids. As a result, explicit expressions for the transport coefficients and macroscopic conservation laws are obtained in the first order for gradients of hydrodynamic parameters. In some particular cases, these expressions are reduced to those corresponding to the well-known Enskog, Davis-Rice-Sengers, and mean-field kinetic theories. It is demonstrated that our approach allows an accurate reproduction of experimental and molecular dynamics data for the transport coefficients of liquid argon in a wide density-temperature range.
