Flame Front Analysis in Turbulent Combustion
نویسندگان
چکیده
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 Rayleigh scattering were carried out in a Bunsen type ame, which yields state of the art but noisy images. Nonlinear anisotropic di usion of edge-enhancing type [1] is shown here to enhance the capabilities of the laser-imaging technique in terms of ame front localization and correlation analysis.

Role of flame-front instability in expanding turbulent flames
Since most of the practical combustion devices operate in turbulent environments, study of turbulent combustion is fundamentally appealing and practically important. Turbulence enhances the flame propagation by wrinkling an otherwise laminar smooth flame, leading to an increase in the flame surface area and hence the total burning rate. There have been number of studies performed to achieve a s...
متن کاملLagrangian formulation of turbulent premixed combustion.
The lagrangian point of view is adopted to study turbulent premixed combustion. The evolution of the volume fraction of combustion products is established by the Reynolds transport theorem. It emerges that the burned-mass fraction is led by the turbulent particle motion, by the flame front velocity, and by the mean curvature of the flame front. A physical requirement connecting particle turbule...
متن کاملCoupling tabulated chemistry with large-eddy simulation of turbulent reactive flows
A new modeling strategy is developed to introduce tabulated chemistry methods in LES of turbulent premixed combustion. The objective is to recover the correct laminar flame propagation speed of the filtered flame front when subgrid scale turbulence vanishes. The filtered flame structure is mapped by 1-D filtered laminar premixed flames. Closure of the filtered progress variable and the energy b...
متن کاملA high-order public domain code for direct numerical simulations of turbulent combustion
A high-order scheme for direct numerical simulations of turbulent combustion is discussed. Its implementation in the massively parallel and publicly available PENCIL CODE is validated with the focus on hydrogen combustion. This is the first open source DNS code with detailed chemistry available. An attempt has been made to present, for the first time, the full set of evolution and auxiliary equ...
متن کاملOn the Dependence of Soot Formation and Combustion on Swirling Combustion Furnaces: Measurement and Simulation
Soot concentration distribution is investigated both numerically and experimentally in methane-air diffusion flame. The experimental work is conducted with a cylindrical swirl stabilized combustor. Filter paper technique is used to measure soot volume fraction inside the combustor. The numerical simulation is based on the solution of the fully-coupled conservation equations for swirling turbule...
متن کاملTheory of High Frequency Acoustic Wave Scattering by Turbulent Flames
This paper describes an analysis of acoustic wave scattering by turbulent premixed flames with moving, convoluted fronts that have random and possibly fractal characteristics. Such interactions play a role in the characteristic unsteadiness observed in turbulent combustion processes. The problem is posed with an integral formulation of the wave equation and assumes that the smallest scales of f...
