Numerical study of premixed flame dynamics in a closed tube: Effect of wall boundary condition
, 2020Numerical simulations were conducted to study the dynamics of premixed flames propagating in a closed tube by solving the fully compressible reactive Navier–Stokes equations using a high-order numerical method on a dynamically adapting grid. A simplified

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 ...

Experimental study of stratified swirl flame dynamics in a model gas turbine combustor
, 2020The flame structure and dynamic response of stratified swirl flames are investigated using a stratified premixed swirl burner. The change of swirl intensity is achieved by swirlers with different swirl angles.

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.

Flame dynamics analysis of highly hydrogen-enrichment premixed turbulent combustion
, 2020The highly hydrogen blended turbulent natural gas flames were stabilized on a nozzle-type Bunsen burner and measured with laser diagnostic technique. Flame topology characteristics and turbulent burning velocities for the lean turbulent combustion and ...
