Digital Library of Periodicals of National Academy of Sciences of UkraineРезюме: | The aim of this review article is to present recent advances in the generalized hydrodynamics of dense gases and liquids. The presentation attempts to integrate the results known previously with the perspective of the
nonequilibrium theory of fluids, but special attention is given to the formalism of generalized collective modes (GCM). This approach allows us to
describe consistently the dynamics of fluids in a wide range of wavevectors and frequencies, starting from the hydrodynamic values and up to the
Gaussian limit, and to perform the calculation of time correlation functions
and generalized transport coefficients within the unified scheme. We start
with the basic equations of the theory. Applications of the GCM approach to
the studies of dynamical properties of various fluid systems (the Lennard-Jones fluid, metallic Cs, binary mixtures and polar liquids) are then discussed. It is shown how the method can be used in the investigations of
magnetic fluids and multicomponent mixtures. Illustrating results, obtained
for the GCM spectra of various systems, are presented. Experimental evidence is cited in favour of the observable propagating kinetic modes found
in the theory. A limited discussion is given to the mode coupling effects. The
relationship to other methods used in the theory of fluids is also discussed. |
