Incomplete molecular chaos within dense-fluid shock waves.
Large-scale molecular dynamics simulations of an M(s) = 4.3 shock in dense argon (rho = 532 kg m(3), T = 300 K) and an M(s) = 3.6 shock in dense nitrogen (rho = 371 kg m(3), T = 300 K) have been performed. The two-point molecular velocity correlation function is calculated within slices in plane with the shock wave. Long-range (approximately ten molecular radii) positive correlations (correlati...

متن کاملWell-posed two-temperature constitutive equations for stable dense fluid shock waves using molecular dynamics and generalizations of Navier-Stokes-Fourier continuum mechanics.
Guided by molecular dynamics simulations, we generalize the Navier-Stokes-Fourier constitutive equations and the continuum motion equations to include both transverse and longitudinal temperatures. To do so we partition the contributions of the heat transfer, the work done, and the heat flux vector between the longitudinal and transverse temperatures. With shockwave boundary conditions time-dep...
متن کاملShock Waves
Shock wave theory was first studied for gas dynamics, for which shocks appear as compression waves. A shock wave is characterized as a sharp transition, even discontinuity in the flow. In fact, shocks appear in many different physical situation and represent strong nonlinearity of the physical processes. Important progresses have been made on shock wave theory in recent years. We will survey th...
متن کاملMolecular dynamics of a dense fluid of polydisperse hard spheres
Slow dynamics in a fluid are studied in one of the most basic systems possible: polydisperse hard spheres. Monodisperse hard spheres cannot be studied as the slow down in dynamics as the density is increased is preempted by crystallisation. As the dynamics slow they become more heterogeneous, the spread in the distances traveled by different particles in the same time increases. However, the dy...
