Pressure-gain combustion has gained attention for airbreathing ramjet engine applications owing to its better thermodynamic efficiency and fuel consumption rate. In contrast with traditional detonation induced by a single wedge, the present study considers oblique shock interactions attached double wedges in hypersonic combustible flow. The temperature/pressure increases sharply across interact...

Mechanical stimuli in energetic materials initiate chemical reactions at shock fronts prior to detonation. Shock sensitivity measurements provide widely varying results, and quantum-mechanical calculations are unable to handle systems large enough to describe shock structure. Recent developments in reactive force-field molecular dynamics (ReaxFF-MD) combined with advances in parallel computing ...

We study an initial-boundary value problem for a singularly perturbed reaction–convection–diffusion system. Asymptotic analysis is used to construct a domain decomposition method for the system to describe the asymptotic nature of the interactions between the boundary layers, interior layers and shock layers. Our results show that the formation of boundary layers and shock layers depends upon i...

background: the aim of this study is to create an ex vivo model to examine the expression of two heat shock protein 70 (hsp70) family members, heat shock protein 72 (hsp72) and heat shock constitute protein 70 (hsc70), at the mrna and protein levels in differentiating corneal cells from air exposed limbal stem cells. materials and methods: limbal biopsies were cultured as explants on a cellular...
