Numerical simulation of dynamics of premixed flames: flame instability and vortex–flame interaction

Progress in Energy and Combustion Science, 2005
Abstract 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, 2000
Abstract 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

Modeling and analysis of premixed flame dynamics by means of distributed time delays

Progress in Energy and Combustion Science, 2020
The unsteady response of a flame to acoustic or flow perturbations plays a crucial role in thermoacoustic combustion instability. The majority of studies on this subject presents and analyzes flame dynamics in the frequency domain by means of a flame ...

M-shaped flame dynamics

Physics of Fluids, 2019
This article deals with the dynamics of a cylindrical bluff-body-stabilized M-shaped premixed flame at low flow rates. A comparative analysis with classical conical flames was performed. The velocities and flame front field dynamics were studied with the use of numerical methods.

Pore-scale flame dynamics in a one-layer porous burner

Combustion and Flame, 2021
Novel design of one-layer porous burner for experimental studies of the flame front dynamics at pore scale level is proposed. Results of the experimental and numerical studies of non-stationary flame front behavior at pore scale are discussed and ...

Maps of flame dynamics for premixed lean hydrogen-air combustion in a heated microchannel

Energy, 2020
In the present work, flame dynamics are extracted for combustion of premixed lean hydrogen-air in a heated microchannel using numerical simulation. In this simulation, Navier-Stokes equations along with energy and species conservation equations are ...

IMPACT OF STRETCH ON THE FLAME DYNAMICS OF LAMINAR PREMIXED FLAMES

Inter-Noise 2022, 2023
Flame 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 ...

In-situ flame particle tracking based on barycentric coordinates for studying local flame dynamics in pulsating Bunsen flames

Proceedings of the Combustion Institute, 2020
Flame particles (FP) are massless, virtual particles which follow material points on the flame surface. This work presents a tracking algorithm for FPs which utilizes barycentric coordinates.
