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

Thermal-expansion induced cellular flames [PDF]
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.
