Self-Propagating Reactive Fronts in Compacts of Multilayered Particles
Figure 1
Schematic illustration of an idealized compact of five multilayered particles. Note that each particle contains multiple bilayers, but only one is illustrated. The individual layers are assumed to be separated by a premixed region, labeled NiAl, of thickness, . The particles are identical of fixed length mm. The contact area, , between the particles and thickness are the same across the compact, but different values are considered in the computations. The flame is initiated at the leftmost particle, with a thermal “spark” of temperature and width . The grid is schematically shown on the second and third particles. Similar gridding is applied to all particles but is not shown.
