Isosurface Interactions Within Turbulent Premixed Hydrogen and Hydrocarbon Flames
… isosurface interactions in premixed turbulent flames. These interactions for a suitable isosuface corresponding to the reaction zone can be interpreted as flame-flame interactions. Isosurface interactions can be identified with the help of Morse theory of critical points and the local topology …

The impact and fate of aqueous sodium nitrate on hydrocarbon flames
… methane/air and methane/methyl chloride/air flames as a function of equivalence ratios that experienced diffusion of air from the surroundings. The flames were stabilized on a slotted, uncooled burner. The data set was divided into profiles of relative sodium atom concentrations, …

LARGE EDDY SIMULATION OF TURBULENT HYDROGEN FLAMES
… on both premixed and non-premixed hydrogen flames, using well documented experimental configurations for validation. The numerical results are assessed against available measurements, demonstrating the capability of the investigated modeling approaches to reproduce key features of the flow …

Laminar flame propagation in mixtures with compositional stratification at small length scales
The behavior and structure of laminar hydrocarbon flames which propagate parallel to the direction of a periodic gradient of mixture composition was studied both experimentally, using a specially designed burner, and computationally, using a planar numerical model. The variations in local mixture …

Laser diagnostics of soot in hydrocarbon diffusion flames
… to investigate the soot volume fraction in flames. However, the extinction-based technique suffers from relatively high measurement uncertainty due to a low signal-to-noise ratio, as the single-pass attenuation of the laser beam intensity is often insufficient. Multipass techniques can …
