The present study addresses the role of molecular non-equilibrium effects in thermal ignition problems. We consider a single binary reaction of the form A+B → C+C. Molecular dynamics calculations were performed for activation energies ranging betwe

Previous experiments have revealed that shock waves driven through dissipative media may become unstable, for example, in granular gases, and in molecular gases undergoing strong relaxation effects. The current paper addresses this problem of shock s

The present study investigates and addresses the influence of non-equilibrium effects on thermal ignition problems using molecular dynamics simulations. The ignition delay calculations were compared with those obtained at the continuum level using ra

Shocks in granular media have been shown to develop instabilities. We address the role that early stages of shock development have on this type of instability. We look at the evolution of shock waves driven by a piston in a dilute system of smooth in

Shocks in granular media, such as vertically oscillated beds, have been shown to develop instabilities. Similar jet formation has been observed in explosively dispersed granular media. Our previous work addressed this instability by performing discre

When a strong shock propagates through a medium with internal degrees of freedom, the thermal equilibration involves the transfer of the mechanical energy imparted by the shock to the medium's internal modes. In gases, for example, this energy relaxa

Media composed of colliding hard disks (2D) or hard spheres (3D) serve as good approximations for the collective hydrodynamic description of gases, liquids and granular media. In the present study, the compressible hydrodynamics and shock dynamics ar
