Abstract

Atomistic simulations of a strong shock wave in a hard-sphere gas are analyzed in terms of thermodynamic forces and fluxes. Evidence is provided that the Burnett corrections to the heat flux significantly improve the agreement with the computed values over the Navier-Stokes predictions in the shock-front region.
