Multi-Scale Turbulence Injector: a new tool to generate intense homogeneous and isotropic turbulence for premixed combustion

open access: yes, 2010
Nearly homogeneous and isotropic, highly turbulent flow, generated by an original multi-scale injector is experimentally studied. This multi-scale injector is made of three perforated plates shifted in space such that the diameter of their holes and ...

An efficient flamelet progress-variable method for modeling non-premixed flames in weak electric fields

open access: yes, 2017
Combustion stabilization and enhancement of the flammability limits are mandatory objectives to improve nowadays combustion chambers. At this purpose, the use of an electric field in the flame region provides a solution which is, at the same time, easy ...

Mathematical model in the form of vorticity-stream function for porous premixed combustion [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2015
This paper proposes a mathematical model used to numerically simulate behaviors of the two-dimensional laminar premixed combustion in porous media. The governing equations proposed include vorticity-stream function equations.

Investigations on conical lean turbulent premixed hydrogenated natural gas flames

open access: yesFuel Communications
Hydrogen's ability to enhance carbon neutrality in combustion processes puts forward the use of hydrogenated fuels, both in the form of fuel and an energy carrier as a potential decarbonization solution.

Characterization of a 5-nozzle array using premix/micromix injection for hydrogen

open access: yesApplications in Energy and Combustion Science
Hydrogen is one of the most promising fuels to decarbonize energy systems since it has a high specific energy, a carbon-free combustion process, and may be produced sustainably through electrolysis.

Influence of Ambient Pressure on the Jet-Ignition Combustion Performance and Flame Propagation Characteristics of Gasoline in a Constant Volume Combustion Chamber

open access: yesEnergies
Based on a constant volume combustion chamber, the initial ambient pressure effect on gasoline combustion performance and flame propagation of the active and passive pre-chamber ignition systems were studied.
