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

Characterization of a 5-nozzle array using premix/micromix injection for hydrogen
Applications in Energy and Combustion ScienceHydrogen 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.

Cyclic flame propagation in premixed combustion
Journal of Fluid Mechanics, 2013 AbstractIn experiments of hot surface ignition and subsequent flame propagation, a puffing flame instability is observed in mixtures that are stagnant and premixed prior to ignition. By varying the size of the hot surface, power input, and combustion vessel volume, it was determined that the instability is a function of the interaction of the flame ...
