Abstract: The structure and stabilization of heated hydrogen jet flames in heated cross-flows was experimentally investigated in a configuration that is analogous to terrestrial gas turbine components. Three flames, with jet velocities ranging from 100-200 m/s, were investigated using particle image velocimetry and OH planar laser induced fluorescence in a total of 11 x − y and y − z planes. Additionally, laser Raman scattering was performed in the 200 m/s jet to characterize the thermo-chemical state. In all cases, the… Show more

“…The mean and instantaneous heat release rate fields in Fig. 2 show that there are two intense heat releasing regions similar to those observed in experiments [29]. These two regions correspond to the flame edges of the two branches.…”

“…The upstream zone is located inside the LW sampling region and the second zone is located further downstream, spanning both the windward and leeward sides. The upstream explosive zones exist primarily on the lean side characterized by a lean partially premixed flame in a conventional lee-stabilized branch [29], while the intense heat release rate regions (see Q • = 0.8, 0.7 contour line in Fig. 3) in the flame base exist slightly on the rich side.…”

“…The jet-in-crossflow (JICF) configuration studied here finds applications in an array of engineering problems and therefore has been studied extensively over the past years in nonreacting and reacting flows [3,[13][14][15][16]. JICFs exhibit highly strained regions of non-uniform mixing, reaction rate, and temperature, and therefore mimic conditions of technical relevance.…”
