DOI: 10.1016/j.jlp.2017.04.018
Abstract: Deflagration-to-detonation transition can occur in industrial explosions involving highly reactive gas mixtures such as H_2/air. Large degrees of confinement and congestion support strong flame acceleration and the transition to detonation. Various mechanisms can accomplish the… read more here.

DOI: 10.1063/1.5093990
Abstract: Two-dimensional, meso-resolved numerical simulations are performed to investigate the complete shock-to-detonation transition (SDT) process in a mixture of liquid nitromethane (NM) and air-filled, circular cavities. The shock-induced initiation behaviors resulting from the cases with neat… read more here.
