Line 9:
Under certain conditions, mainly in terms of geometrical conditions (such as partial confinement and many obstacles in the flame path that cause turbulent flame eddy currents), a subsonic flame front may accelerate to supersonic speed, transitioning from deflagration to detonation. The exact mechanism is not fully understood,<ref name=GexCon>{{cite web|title=Chapter 6: Detonation |url= http://www.gexcon.com/index.php?src=handbook/GEXHBchap6.htm |website=Gexcon AS |archive-date=October 4, 2011 |archive-url=https://web.archive.org/web/20111004174240/http://www.gexcon.com/handbook/GEXHBchap6.htm}}</ref>
and while existing theories are able to explain and model both deflagrations and detonations, there is no theory {{as of|2023|alt=at present}} which can predict the transition phenomenon.
==Examples==
A deflagration to detonation transition has been a feature of several major [[industrial accident]]s:
* [[1970
* [[Flixborough disaster]]
* [[Phillips disaster of 1989]] in Pasadena, Texas
* Damage observed in the [[Buncefield fire]]
* [[2020 Beirut explosions
==Applications==
