Improvement of Municipal Solid Waste Syngas Premixed Flame with Cellular Structure on a Flat Burner [PDF]

open access: yesEnergies, 2023
This research was conducted to study the flame instability of syngas derived from raw municipal solid waste (MSW) and its potential as a natural gas (NG) replacement in power generation. MSW syngas is a mixture of various components such as methane (CH4),

Investigation of cellular instabilities and local extinction for two-phase flames under microgravity conditions [PDF]

open access: yesComptes Rendus. Mécanique, 2023
The initial mechanism of cellular instabilities on the flame surface was investigated experimentally. Firstly, mono-dispersed ethanol droplets were created via the Wilson cloud principle in a spherical combustion chamber, and aerosol ethanol/air flame ...

Formation of Cellular Flames and Increase in Flame Velocity Generated by Intrinsic Instability.

open access: yesTransactions of the Japan Society for Aeronautical and Space Sciences, 2002
The formation of cellular flames and the increase in flame velocity generated by intrinsic instability are studied by two-dimensional (2-D) and three-dimensional (3-D) unsteady calculations of reactive flows based on the compressible Navier-Stokes equation.

Study on flame fractal characteristics of coal dust explosion at the decompression position of Hartmann tube [PDF]

open access: yesScientific Reports
The explosion of coal dust is powerful and has a wide range of spread, which can easily cause mass death and injury. In this paper, the flame microstructure and propagation characteristics of coal dust explosion are recorded by high-speed photography ...

Stability study of flame structure using photodiodes in surface flame burners [PDF]

open access: yesScientific Reports
Radiation spectroscopy can be effective in identifying pollutants and species. By examining a photodiode, the frequency peaks obtained from the analysis, and the range in which the cell flame is converted to a surface flame, we obtained the value ratio ...

Effects of pressure and heat loss on the unstable motion of cellular-flame fronts caused by intrinsic instability in hydrogen-air lean premixed flames

open access: yesJournal of Thermal Science and Technology, 2021
Effects of pressure and heat loss on the unstable motion of cellular-flame fronts in hydrogen-air lean premixed flames were numerically investigated. We adopted the reaction mechanism for hydrogen-oxygen combustion, modeled with seventeen reversible ...

Thermal-expansion induced cellular flames [PDF]

open access: yesCombustion and Flame, 1982
Abstract This paper is devoted to a study of the nonlinear evolution of a disturbed plane flame front in a hydrodynamic instability regime induced by thermal expansion of a burned gas. It is shown that, in sufficiently small-scale flames, spontaneous instability appears in the guise of stationary wide-spaced irregular folds.

The shape and fluctuation of hydrogen-propane-butane-air lean premixed flames formed on a flat flame burner

open access: yesJournal of Thermal Science and Technology, 2021
In this paper, the characteristics of hydrogen-propane-butane-air lean premixed flames on a flat flame burner were experimentally studied. To elucidate the shape and fluctuation of premixed flames, the cell width, RMS of fluctuation, peak frequency and ...
