Extinction of laminar partially premixed flames
Progress in Energy and Combustion Science, 2009Flame extinction represents one of the classical phenomena in combustion science. It is important to a variety of combustion systems in transportation and power generation applications. Flame extinguishment studies are also motivated from the consideration of fire safety and suppression.

Effect of pressure on counterflow H2–air partially premixed flames
Combustion and Flame, 2005A computational investigation of high-pressure hydrogen–air partially premixed flames (PPFs) is reported to characterize the effect of pressure on the flame structure, and the relevance of reaction limits for these flames. The flames are computed using the Mueller mechanism consisting of 19 elementary reactions and 9 species. Although the mechanism has

Simulation of Premixed and Partially Premixed Jet-in-Crossflow Flames at High-Pressure
Volume 4B: Combustion, Fuels, and Emissions, 2020Abstract In this paper we explore the operational map of a lean axial-staged combustor of premixed and partially premixed reacting jet-in-crossflow flames at high-pressure (5 atm). This study attempts to expand the data to relatively high pressure and could significantly aid scaling to real gas turbine engine conditions at 20–30 atm ...

Extinction of partially premixed flames
Proceedings of the Combustion Institute, 2002Experimental and numerical studies on extinction of laminar partially premixed flames are carried out. The studies are performed in the counterflow configuration. A premixed fuel-rich mixture of methane (CH 4 ), oxygen (O 2 ), and nitrogen (N 2 ) is injected from one duct while a fuel-lean mixture of CH 4 , O 2 , and N 2 is injected from the other ...

Flame stretch effects on partially premixed flames
Combustion and Flame, 2000Abstract Flame stretch is an important characteristic of flame behavior that arises due to flow motion and nonuniformity, and flame curvature. Various investigators have obtained different expressions for flame stretch by employing dissimilar analytical approaches for diverse flame configurations.
