Structural features of highly turbulent piloted flames were acquired from simultaneous PLIF images of formaldehyde (CH2O) and OH. Both lean and near-stoichiometric (equivalence ratio ϕ= 0.75 and 1.05, respectively) methane-air flames were studied under twelve different flow conditions and at two different interrogation regions. The non-reacting conditions for these flames consist of turbulent Reynolds numbers (ReT), turbulence intensities (u’/SL), and integral length scales that range from 520 to 80,000; 5 to 185; and 6 mm to 37 mm, respectively. Eight of the twelve cases have u’/SL> 25 and thus are classified into a regime of extreme turbulence. Preheat and reaction zone thicknesses were measured in all twelve cases. The preheat zone thickness was interpreted from the CH2O PLIF images and the reaction zone thicknesses were obtained from the profiles derived from the pixel-by-pixel product of the OH and CH2O PLIF images. The preheat zones associated with a particular condition were classified as being “thickened” if the mean thickness for that condition exceeded two but not four times the measured laminar value (0.42 and 0.39 mm for lean and rich flames, respectively). If the average thickness was greater than four times the measured laminar value that preheat zone was deemed “primarily distributed.” Ten of the twelve cases possessed “primarily distributed” preheat zones, while those in the two least turbulent cases were “thickened.” The majority of the cases possessed average reaction layer thicknesses that are no thicker than twice the measured laminar value (0.39 and 0.38 mm for lean and rich flames, respectively); hence, they were identified as having “thin” reaction layers. Regardless of being categorized as “thin,” the reaction zones in each case exhibited regions of both relatively thin and thick reaction layers. In fact the appearance of the observed reaction zones can best be described as resembling “chicken noodle soup.” That is, in any given instantaneous image relatively thin,“noodle-like” reaction layers are generally accompanied by thicker “chunky-chicken-like” reaction regions. Furthermore, the observed reaction zone structures in a particular case often fail to correspond to those predicted by the turbulent premixed combustion regime diagram. This suggests that the regime diagram requires alterations if it is to properly forecast the appearance of a flame based on a simple set of operating conditions. The data set presented here is currently too limited to enable a thorough re-mapping of the regime diagram. However, based on their structural features, the cases considered here were categorized into appropriate regimes of combustion.
