Structurally stable atomistic one-dimensional shock waves have long been simulated by injecting fresh cool particles and extracting old hot particles at opposite ends of a simulation box. The resulting shock profiles demonstrate tensor temperature, Txx≠Tyy and Maxwell's delayed response, with stress lagging strain rate and heat flux lagging temperature gradient. Here this same geometry, supplemented by a short-ranged external "plug" field, is used to simulate steady Joule-Kelvin throttling flow…

Transient Heat Flow in a One-component Lennard-Jones/spline Fluid. A Non-equilibrium Molecular Dynamics Study
A one-component Lennard-Jones/spline fluid at equilibrium was perturbed by a sudden change of the temperature at one of the system’s boundaries. The system’s response was determined by
Theory and simulation of shock waves: Entropy production and energy conversion.
TLDR
The GEM showed that most of the shock's kinetic energy was converted reversibly into enthalpy and entropy, and a small amount was dissipated as produced entropy, while the overpressure determined from NEMD simulations agreed well with the Rankine-Hugoniot conditions for steady-state shocks.
Simulation of Joule-Thomson Throttling of Gases
A complete general theory for non-equilibrium states is currently lacking. Non-equilibrium states are hard to reproduce experimentally, but creating computer simulations of relatively simple and

Equilibration of kinetic temperatures in face-centered cubic lattices.
TLDR
It is shown that in the anharmonic case the approach to thermal equilibrium has two time scales, and a universal curve describing equilibration in the Lennard-Jones crystal over a wide range of temperatures is obtained.

Tensor temperature and shock-wave stability in a strong two-dimensional shock wave.
TLDR
The anisotropy of temperature is studied here in a strong two-dimensional shock wave, simulated with conventional molecular dynamics, and the decay of sinusoidal shock-front perturbations shows that strongTwo-dimensional planar shock waves are stable to such perturbation.
