Stationary Flame Front in a Swirl Combustion Chamber

Flame Front Analysis in Turbulent Combustion

Fundamental research of turbulent combustion often requires the unambiguous localization of ame front positions and structures. Laser-induced uorescence (LIF) imaging provides di erent possibilities of detecting two-dimensional distributions of species typical for reactive areas. Simultaneous measurements of hydroxyl and formaldehyde laserinduced uorescence and total number densities by Rayleig...

Effect of Swirl on Gas-Fired Combustion Behavior in a 3-D Rectangular Combustion Chamber

The objective of this work is to investigate the turbulent reacting flow in a three dimensional combustor with emphasis on the effect of inlet swirl flow through a numerical simulation. Flow field is analyzed using the SIMPLE method which is known as stable as well as accurate in the combustion modeling, and the finite volume method is adopted in solving the radiative transfer equation. In this...

The Effect of Intake Flow Modelling on Flame Front Shape and Its Displacement in Cylindrical Combustion Chamber

In this paper some results concerning the effect of intake flow modeling obtained by 3D numerical modeling of combustion on flame front shape and its displacement through combustion chamber geometry of s.i .engine consisting of flat head with two ver tical valves and cylindrical bowl were presented. These results obtained with KIVA3V code were compared with results of flame front shape and its ...

A Fully Nonlinear Equation for the Flame Front in a Quasi-steady Combustion Model

We revisit the Near Equidiffusional Flames (NEF) model introduced by Matkowsky and Sivashinsky in 1979 and consider a simplified, quasisteady version of it. This simplification allows, near the planar front, an explicit derivation of the front equation. The latter is a pseudodifferential fully nonlinear parabolic equation of the fourth-order. First, we study the (orbital) stability of the null ...
