Preface to the Special Issue

This Special Issue includes selected research papers expanded from work that was presented at the 25th International Colloquium on the Dynamics of Explosions and Reactive Systems (ICDERS), held August 2–August 7, 2015, at the University of Leeds, England. As with all prior ICDERS, the topics at this colloquium comprise two general categories: (1) the dynamics of explosions, exploring the interrelationship between energy deposition in compressible media and the flow field, as occurs typically in detonations; and (2) the dynamics of reactive systems, studying the steady and nonsteady coupling between flow systems and exothermic reactions occurring within them, as occurs typically in deflagrations. In the 25th Colloquium, several special topics sessions were organized, and the papers in this issue reflect some of these as well. The results of analytical, computational, and experimental research from around the world on these topics are presented at the colloquium. More than 300 researchers from 21 countries attended the 25th ICDERS, and they presented 211 podium papers plus 63 poster papers on explosions, detonations, ignition, turbulent flames, laminar flames, and heterogeneous combustion, among other topics. The selected papers from the 25th ICDERS in this issue comprise articles that include turbulent combustion, novel combustion systems, flame structure and stability, ignition, detonations, detonation engines, and deflagration-to-detonation transitions. From this range of topics, it is evident that the papers represent the broad spectrum of the dynamics of explosions and reactive systems we expect from the ICDERS. Prior to 1993, the American Institute of Aeronautics and Astronautics published selected presentations from ICDERS in the series on Progress in Astronautics and Aeronautics. For the colloquia in the period 1993–2009, the authors were given the opportunity to submit their presented papers for review for publication in either Combustion Science and Technology or Shock Waves: An International Journal on Shock Waves, Detonations, and Explosions. Beginning in 2001, these two options were augmented by including Combustion Theory and Modelling as a third journal to which papers can be submitted. The Special Issues of Combustion Science and Technology that were generated from previous International Colloquia on the Dynamics of Explosions and Reactive Systems were published in Volume 105 (Nos. 4–6), 1995; Volumes 113–114, 1996; Volume 135 (Nos. 1–6), 1998; Volume 158, 2000; Volume 174 (Nos. 5–6), 2002; Volume 176 (No. 10), 2004; Volume 178 (Nos. 10–11), 2006; Volume 180 (Nos. 10–11), 2008; Volume 182 (Nos. 11–12), 2010; Volume 184 (Nos. 10–11), 2012; and Volume 186 (Nos. 10–11), 2014. The forthcoming 26th ICDERS will be held during the summer of 2017 in Boston, Massachusetts, USA. A Special Issue of Combustion Science and Technology is planned for selected publications from this Colloquium as well. This special issue would not have been possible without the enthusiasm and responsiveness of authors and many conscientious and thoughtful peer reviewers of both the conference submissions and the enhanced versions submitted to the special issue.
