Extinction of Laminar Partially Premixed Flames

Progress in Energy and Combustion Science, 2009
Flame 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.

Modelling and Calculation of a Partially Premixed Turbulent Flame

open access: yesCombustion Science and Technology, 1999
A partially premixed turbulent flame has been modelled using the laminar flamelet concept, i.e. the assumption that laminar flames are embedded in the turbulent flow field. A combination of a premixed flamelet model and a diffusion flamelet model has been used for modelling this partially premixed flame.

On Scalar Dissipation and Partially Premixed Flame Propagation

Combustion Science and Technology, 2003
Measurements of the scalar dissipation rate in the region immediately upstream of a lifted jet flame are presented. The scalar dissipation is determined in this isothermal region from a planar measurement of a two-dimensional conserved scalar (jet fluid) using laser Rayleigh scattering. Fields of the scalar dissipation rate are presented in addition to

An Experimental Study of Partially Premixed Flame Sound

Proceedings of the Combustion Institute, 2005
Abstract The occurrence of oscillating combustion and combustion instability has led to resurgence of interest in the causes, mechanisms, suppression, and control of combustion noise. Noise generated by enclosed flames is of greater practical interest but is more complicated than that by open flames, which itself is not clearly understood.

Simulation of Premixed and Partially Premixed Jet-in-Crossflow Flames at High-Pressure

Volume 4B: Combustion, Fuels, and Emissions, 2020
Abstract 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, 2002
Experimental 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 ...
