Page • Many reacting flows are inherently three dimensional and temporally evolving. High-speed 3D imaging measurements are required to capture the dynamics of key processes such as localized extinction and re-ignition in turbulent combustion. To meet that need, we have combined multi-kHz rate tomographic particle image velocimetry (tomo-PIV) and laser-induced fluorescence (LIF)...
