Experimentally measured burning rates of premixed turbulent flames

DNS analysis of propagation speed and conditional statistics of turbulent premixed flame in a planar impinging jet

“…(7). The S C 's are lower than the S T 's due to divergence of the reactant flow as reported in previous experiments [3,25].…”

Measured properties of turbulent premixed flames for model assessment, including burning velocities, stretch rates, and surface densities

“…This promotes the highly wrinkled, corrugated flame conditions that lead to flamelet merging and the "bending" phenomenon that has been reported in Refs. [27][28][29][30][31][32].…”

Measurements of the heat release rate integral in turbulent premixed stagnation flames with particle image velocimetry

“…Thus, one can expect the same densityweighted reaction rate for both C T and C h progress variables as (15) …”

“…(1), its experimental determination is not straightforward. Methods have since been proposed that are either based on postprocessing of the twodimensional local flame contours [13] or from point measurements of the conditional mass flux [14][15][16][17]. These early attempts, however, have been questioned regarding the appropriateness of the assumptions involved and the accuracy of evaluation techniques used.…”

“…In addition, Eq. (1) is explored with a different approach such that the turbulent consumption speed is determined locally along the flame brush surface, in contrast to the global turbulent consumption speed measured in a control volume of finite flame brush surface area [13][14][15][16][17][18]. Furthermore, a new definition that is based on the heat release rate integral rather than that of the fuel mass burning rate is proposed for experimental determination of the turbulent consumption speed.…”
