Numerical simulation of dynamics of premixed flames: flame instability and vortex–flame interaction
Progress in Energy and Combustion Science, 2005Abstract The characteristics of cellular flames generated by intrinsic instability has been studied using two-dimensional (2-D) and three-dimensional (3-D) unsteady calculations of reactive flows, based on the compressible Navier–Stokes equation.

Dynamics of flame/vortex interactions
Progress in Energy and Combustion Science, 2000Abstract Vortex interactions with flames play a key role in many practical combustion applications. Such interactions drive a large class of combustion instabilities, they control to a great extent the structure of turbulent flames and the corresponding rates of reaction, they occur under transient operations or when flames travel in ducts containing

IMPACT OF STRETCH ON THE FLAME DYNAMICS OF LAMINAR PREMIXED FLAMES
Inter-Noise 2022, 2023Flame transfer functions (FTF) of laminar premixed flames acoustically forced are analytically investigated and modelled. The study is based on the linearized G-equation, which is used to kinematically track the flame front. In order to incorporate combustion properties, the laminar consumption speed is considered varying depending on the flame front ...

Nonlinear Dynamics of Cellular Flames
SIAM Journal on Applied Mathematics, 1992The problem of a flame stabilized by a line source of fuel in the cellular regime, i.e., $L < 1$,where L is the Lewis number, is solved numerically. It is found that as L is decreased, transitions from stationary axisymmetric to stationary cellular to nonstationary cellular flames occur.

Annual Review of Fluid Mechanics, 2014
In many continuous combustion processes, such as those found in aeroengines or gas turbines, the flame is stabilized by a swirling flow formed by aerodynamic swirlers. The dynamics of such swirling flames is of technical and fundamental interest. This article reviews progress in this field and begins with a discussion of the swirl number, a parameter ...

On the dynamics of anchored flames
Combustion and Flame, 1990The dynamic and the shape of an anchored premixed flame are analyzed as the result of the sum of wrinkles convected along the flame and of the wrinkles locally induced by the flow. The linear approximation leads to an interference integral that describes the shape as a function of time.

On the Dynamics of a Bunsen Flame
2006The stabilization of a Bunsen flame above the burner rim is simulated using the method of characteristics. Oscilliations of the flame front and of its area due to flow oscilliations are computed.

Flame Root Dynamics and Their Role in the Stabilisation of Lifted Flames
2021This chapter aims to provide a broad overview on the importance of lifted flames in turbulent flows with and without swirl in practical applications for energy production and propulsion. The stabilisation of lifted flames is governed by numerous physical processes that control the behaviour of the flame root or the leading edge.
