Premixed flames in a stagnation point flow under Darcy's law
Prabakaran Rajamanickam, Joel Daou
Premixed flames in stagnation point flows are traditionally described using Navier--Stokes equations where inertia and density variations play an important part in determining the…
Hydrodynamic theory of premixed flames under Darcy's law: Interfacial conditions and effects of nonunity Lewis number and heat loss
Prabakaran Rajamanickam, Joel Daou
Premixed flames propagating in porous media or Hele-Shaw channels are governed by Darcy's law, which accounts for the strong frictional forces imposed by the solid matrix or confin…
Flame dynamics and Markstein numbers in Hele-Shaw cells and porous media under Darcy's law
Prabakaran Rajamanickam, Joel Daou
The propagation of premixed flames in narrow Hele-Shaw cells and permeable porous media is governed by Darcy's law, leading to hydrodynamic behaviour distinct from conventional fla…
Premixed flame quenching distance between cold walls: effects of flow and Lewis number
Aiden Kelly, Rémi Daou, Joel Daou +2
This study investigates the critical conditions for flame propagation in channels with cold walls. We analyze the impact of the Lewis number and flow amplitude () on the minimum…
Hydrodynamic theory of premixed flames under Darcy's law
Prabakaran Rajamanickam, Joel Daou
This paper investigates the theoretical implications of applying Darcy's law to premixed flames, a topic of growing interest in research on flame propagation in porous media and co…
Hydrodynamic instabilities of propagating interfaces under Darcy's law
Joel Daou, Prabakaran Rajamanickam
The hydrodynamic instabilities of propagating interfaces in Hele-Shaw channels or porous media under the influence of an imposed flow and gravitational acceleration are investigate…
Effect of a shear flow on the Darrieus-Landau instability in a Hele-Shaw channel
Prabakaran Rajamanickam, Joel Daou
The Darrieus--Landau instability of premixed flames propagating in a narrow Hele-Shaw channel in the presence of a strong shear flow is investigated, incorporating also the Rayleig…
Tricritical point as a crossover between type-I and type-II bifurcations
Prabakaran Rajamanickam, Joel Daou
A tricritical point as a crossover between (stationary finite-wavelength) type-I and (stationary longwave) type-II bifurcations is identified in the study of diffusive-ther…
Three-dimensional diffusive-thermal instability of flames propagating in a plane Poiseuille flow
Aiden Kelly, Prabakaran Rajamanickam, Joel Daou +1
The three-dimensional diffusive-thermal stability of a two-dimensional flame propagating in a Poiseuille flow is examined. The study explores the effect of three non-dimensional pa…
Effective Lewis number and burning speed for flames propagating in small-scale spatio-temporal periodic flows
Prabakaran Rajamanickam, Joel Daou
Propagation of premixed flames having thick reaction zones in rapidly-varying, small-scale, zero-mean, spatio-temporal periodic flows is considered. Techniques of large activation…
Diffusive-thermal instabilities of a planar premixed flame aligned with a shear flow
Joel Daou, Prabakaran Rajamanickam
The stability of a thick planar premixed flame, propagating steadily in a direction transverse to that of unidirectional shear flow, is studied. A linear stability analysis is carr…
