Abstract: | A systematic approach to derivation of hydrodynamic-like balance equations for systems with a smooth continuous potential
as well as hard sphere repulsion is represented. Cases of many-particle local and two-particle nonlocal hydrodynamic densities
are considered. The results are applied for construction of balance equations for fluxes of momentum and energy, which form
the first extension of conventional hydrodynamics. Explicit balance equations for the stress tensor and the heat flux in the
local frame of reference are obtained. |
