Consistent Description of Kinetics and Hydrodynamics of Weakly Nonequilibrium Processes in Simple Liquids

The generalized transport equations for a consistent description of kinetic and hydrodynamic processes in dense gases and liquids are considered and the intrinsic structure of the generalized transport kernels for these equations is established. As a result, we show how to obtain the transport equation of molecular hydrodynamics in our approach. We also investigate the spectrum of collective modes for a system with the model potential of interaction presented as a sum of the hard sphere and long-range parts.
