Abstract

Flames are loosely defined as a coupled multiscalar manifold. The multiscalar fields represent the chemical composition of the flame. In turbulent flows, the topology of this field changes dynamically. Typical hydrocarbon flames involve up to hundred of chemical species. The study of this complex geometrical object is important from the mathematical and physical point of view. We performed a Direct Numerical Simulation of a turbulent methane-air flame in the regime where extinction holes are observed.
