✦ Synopsis
By use of high-speed planar laser-induced fluorescence (PLIF) imaging, the evolution of turbulent reactive flows was recorded and studied in real time in a filmlike manner. The technique was used to track the concentration field of the OH radical, which was produced during spark ignition of a turbulent methane/air mixture. The results were compared qualitatively to a two-dimensional direct numerical simulation of the same system using a detailed chemical mechanism and a detailed transport model.
