Mechanism of Spontaneous Acceleration of Slow Flame in Channel
FireThis paper is devoted to the numerical analysis of the spontaneous acceleration of a slow flame in a semi-closed channel. In particular, the flow development in the channel ahead of the propagating flame is analyzed.

Dynamic behavior and flame acceleration of outwardly expanding flame in hydrogen-air mixture
Nihon Kikai Gakkai ronbunshu, 2016 From the perspective of safety, it is necessary to assess the risk of hydrogen-air deflagration accurately. Especially, flame propagation velocity is one of the most important factors.

Sectioning of Potential Explosion Domains to Reduce the Severity of a Vapour Cloud Explosion
Chemical Engineering Transactions, 2016 Medium scale vapour cloud explosion experiments demonstrated that the severity of a vapour cloud explosion (VCE) can be reduced substantially by initiating counter fires within a vapour cloud as soon as a developing flame can be detected within the ...
