Effect of Stretch on Local Burning Velocity of Premixed Turbulent Flames
Journal of Thermal Science and Technology, 2007 The effect of positive stretch on the local flame properties of turbulent propagating flames in the flamelet regime was investigated experimentally for methane-, hydrogen- and propane-air mixtures with lean and rich having nearly the same laminar burning

Journal of Thermal Science and Technology, 2010 Asymptotic analysis on premixed flames with high-temperature combustible mixtures was performed to elucidate the instability of flame fronts. Planar premixed flames with sufficiently low Mach numbers were treated, and a one-step irreversible chemical ...
