Derivation of hydrodynamic equations for dense gaseous mixtures with multi-step interaction between particles

M.V. Tokarchuk
Y.A. Humenyuk

Generalization of the kinetic equation for a dense gas with a multi-step interaction potential to the case of a dense mixture is carried out. Derivation of hydrodynamic equations is performed starting from the kinetic equation for the one-particle distribution function and the transport equation for the potential energy density. General expressions for momentum and heat fluxes are obtained. The transport equation for the kinetic energy density is shown to contain a new term of the "source" type, which describes fast exchange processes between kinetic and potential energies of the system.
