Instability of lean H2-O2-CO2 premixed flames on a flat burner
Nihon Kikai Gakkai ronbunshu, 2015 Global warming and air pollution mainly caused by emissions of CO2 and NOx are serious problems. We focus on a lean H2-O2 premixed flame because H2-O2 premixed flame emits no CO2 and NOx.

Modelling of turbulent lifted jet flames using flamelets: a priori assessment and a posteriori validation [PDF]
, 2014 This study focuses on the modelling of turbulent lifted jet flames using flamelets and presumed PDF approach with interests on both flame lift-off height and flame brush structure.

Premixed-flame shapes and polynomials [PDF]
Physica D: Nonlinear Phenomena, 2015 The nonlinear nonlocal Michelson-Sivashinsky equation for isolated crests of unstable flames is studied, using pole-decompositions as starting point. Polynomials encoding the numerically computed 2N flame-slope poles, and auxiliary ones, are found to closely follow a Meixner Pollaczek recurrence; accurate steady crest shapes ensue for N>=3. Squeezed

An extended flame index partitioning for partially premixed combustion
, 2020 Compared to partially premixed combustion (or combustion of non-homogeneous reactants in general), fully premixed and diffusion flames represent only two asymptotic limits of combustion modes.

An experimental study on coflow diffusion combustion in a pellet-packed bed with different bed lengths [PDF]
Royal Society Open Science, 2018 In experimental investigations on axial symmetry, over-ventilated CH4/air diffusion combustion in a packed bed is executed to study the height, shape and stability of the flame.

Large Eddy Simulation of combustion instabilities in a lean partially premixed swirled flame [PDF]
, 2012 This paper investigates one issue related to Large Eddy Simulations (LES) of self- excited combustion instabilities in gas-fueled swirled burners: the effects of incom- plete mixing between the gas injection and the combustion chamber.

Premixed flame dynamics in presence of mist
Combustion Science and Technology, 2018 The injection of a water spray within an enclosure prone to explosion is reputed to reduce the risk. This strategy for safety improvement is at the root of numerous experiments that have concluded that premixed flame can be extinguished by a sufficient ...
