Shock Ignition of Reactive Particles

In this paper we study shock ignition of reactive particles in a shock tube environment. When shock propagates through a dust cloud consisting of reactive particles, the cloud is shifted, compressed, and the internal cloud temperature increased. In most experimental studies a closed-end shock tube is used to allow the shock to reflect and propagate through the cloud a second time, further increasing the dust particle temperature. We use a multi-phase version of the numerical Regularized Smoothed Particle Hydrodynamics (RSPH) method [1], to study shock ignition, and discuss important parameters that affect the particle ignition process.
