INVESTIGATION OF FLAME STRETCH IN TURBULENT LIFTED JET FLAME [PDF]
Combustion Science and Technology, 2014 DNS data of a laboratory-scale turbulent lifted hydrogen jet flame has been analyzed to show that this flame has mixed mode combustion not only at the flame base but also in downstream locations. The mixed mode combustion is observed in instantaneous structures as in earlier studies and in averaged structure, in which the predominant mode is found to ...

Flame stretching by electric field
Journal of Physics: Conference Series, 2019 Abstract The paper considers the issues related to the study of the mechanisms of controlling the combustion of hydrocarbon fuels by electric fields. It is shown that influence of weak electric field on combustion in laminar mode leads to a change in the degree of flame stretching (Karlovitz number).
