Non-equilibrium effects on thermal ignition using hard sphere molecular dynamics simulations

R. Murugesan, N. Sirmas, M. I. Radulescu

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 dynam…

Thermal ignition revisited with two-dimensional molecular dynamics: role of fluctuations in activated collisions

Nick Sirmas, Matei I. Radulescu

The problem of thermal ignition in a homogeneous gas is revisited from a molecular dynamics perspective. A two-dimensional model is adopted, which assumes reactive disks of type A…

Evolution and stability of shock waves in dissipative gases characterized by activated inelastic collisions

Nick Sirmas, Matei I. Radulescu

Previous experiments have revealed that shock waves driven through dissipative gases may become unstable, for example, in granular gases, and in molecular gases undergoing strong r…

Evolution of shock instability in granular gases with viscoelastic collisions

Nick Sirmas, Matei Radulescu

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 evolu…

Instability in Shocked Granular Gases

Nick Sirmas, Sam Falle, Matei Radulescu

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 me…

Shock Waves in Dense Hard Disk Fluids

Nick Sirmas, Marion Tudorache, Javier Barahona +1

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 t…

Shock instability in dissipative gases

Matei I. Radulescu, Nick Sirmas

Previous experiments have revealed that shock waves in thermally relaxing gases, such as ionizing, dissociating and vibrationally excited gases, can become unstable. To date, the m…

Detonation waves via molecular dynamics simulations of reactive hard disks

Nick Sirmas, Matei Radulescu

Videos of the molecular dynamics simulations of a colliding hard disk reactive medium. A simple event-driven algorithm is used to simulate these colliding hard disks allowing for t…
