Flame holes in a reactively, temporally evolving mixing layer —Wang Han, University of Edinburgh

The original picture (without any rendering) shows flame holes (view on top of the center-plane) in a reactively, temporally evolving mixing layer. The fuel stream (Z=1) is composed of 50% CO, 10% H2 and 40% N2 by volume, and the oxidizer stream (Z=0) is composed of 25% O2 and 75% N2. The stoichiometric mixture fraction is Zst=0.42. The reference Reynolds number is 9075. More details can be found in https://doi.org/10.1016/j.combustflame.2019.04.038.
