Experimental two dimensional cellular flames [PDF]

open access: yesPhysics of Fluids, 2015
The propagation of very unstable cellular flames (also called self-turbulent flames) is studied experimentally in a Hele-Shaw cell. This quasi-two dimensional configuration allows for quantitative image analysis. The dynamics of the premixed flame is controlled in these conditions by the creation or merging of the cusps that appear on the front.

Dynamic behavior and flame acceleration of outwardly expanding flame in hydrogen-air mixture

open access: yesNihon Kikai Gakkai ronbunshu, 2016
From the perspective of safety, it is necessary to assess the risk of hydrogen-air deflagration accurately. Especially, flame propagation velocity is one of the most important factors.

Nonlinear cellular instabilities of planar premixed flames: numerical simulations of the Reactive Navier-Stokes equations [PDF]

open access: yes, 2006
Two-dimensional compressible Reactive Navier-Stokes numerical simulations of intrinsic planar, premixed flame instabilities are performed. The initial growth of a sinusoidally perturbed planar flame is first compared with the predictions of a recent ...
