Flame front tracking in turbulent lean premixed flames using stereo PIV and time-sequenced planar LIF of OH
This paper describes the simultaneous application of time-sequenced laser-induced fluorescence imaging of OH radicals and stereoscopic particle image velocimetry for measurements of the flame front dynamics in lean and premixed LP turbulent flames. The studied flames could be acoustically driven, to simulate phenomena important in LP combustion technologies. In combination with novel image post...
متن کاملPremixed-flame shapes and polynomials
The nonlinear nonlocal Michelson-Sivashinsky equation for isolated crests of unstable flames is studied, using pole-decompositions as starting point. Polynomials encoding the numerically computed 2N flame-slope poles, and auxiliary ones, are found to closely follow a MeixnerPollaczek recurrence; accurate steady crest shapes ensue for N3. Squeezed crests ruled by a discretized Burgers equation ...
متن کاملApplication of a Flame Dictionary Method in Turbulent Premixed Flame Modeling. Construction of a Flame Dictionary
|The construction of a ame dictionary of ame speeds and preheat thicknesses for a given reaction will be discussed. Once the entries of the dictionary have been established, they can be accessed by researchers and programmers to be used in diierent combustion applications. An application of the ame dictionary for turbulent combustion in a circular cylinder is given. Chemical reactions are often...
متن کاملLean Premixed Flame Stability Investigations
Fellowship Experience Throughout my twelve-week fellowship at Pratt & Whitney I had the opportunity to interact with numerous engineers and managers as well as to be exposed to a variety of disciplines and areas of engineering. My mentor, Bill Proscia, is an expert in the field of combustion instability analysis and modeling. I gained valuable experience working on a combustion project under hi...
متن کاملFlame Flashback and Propagation of Premixed Flames near a Wall
The flashback or propagation of premixed flames along the near-wall low-velocity region at the base of a laminar boundary layer of a reactive mixture has been studied numerically. The analysis, carried out using the constant density approximation for an Arrhenius overall reaction, accounts for the effects of the Lewis number of the fuel. The flow field, as seen by an observer moving with the fr...
