The propagation of outwardly expanding premixed flames in turbulent media is examined within the context hydrodynamic theory wherein flame, treated as a surface density discontinuity separating fresh combustible mixture from burned products, propagating at speed dependent upon local geometric and mixture/flow characteristics. An embedded manifold approach, one adept handling multi-valued disjoi...

Premixed turbulent flames, encountered in power generation and propulsion engines, are an archetype of a randomly advected, self-propagating surface. While such flame is known to exhibit large-scale intermittent flapping, the possible intermittency its small-scale fluctuations has been largely disregarded. Here, we experimentally reveal inner premixed V-flame, while clearly distinguishing this ...
