The kinetic theory of a dense gas in the approximation of three-body interaction (hydrodynamic approximation) (Q761162)

Using the Bogolyubov method, the kinetic equations for dense gases in the presence of nonadditive three-body forces have been obtained. The account for the three-body interactions is shown to lead to the appearance, in the kinetic equations, of the collision integrals of the same order as that of the Choh-Uhlenbeck integral. Based on these equations the hydrodynamics of dense gases have been developed up to the \(n^ 2\)-order terms and general expressions have been obtained for the viscosity and thermal conductivity coefficients in the approximation of three-body interactions.
