Abstract

A one-dimensional system, consisting of identical hard-rod particles of length a is studied in the hydrodynamical limit. A “Navier–Stokes correction” to the Euler equation is found for an initial local equilibrium family of states P_\epsilon, \epsilon > 0, of constant density. The correction is given, at t > 0, by a non-linear second order differential operator acting on f(q; v); the hydrodynamical density at a point q of the “species” of fluid with velocity v.
