Time-resolved (kHz) 3D imaging of OH PLIF in a flame
(2014) In Experiments in Fluids 55(6). p.1764-1764- Abstract
- Based on scanning planar laser-induced fluorescence of OH, a measurement system with the capability to record time-resolved three-dimensional image sequences of the OH concentration and the flame front is demonstrated on a premixed flame. A dual-mirror scanning system is used to obtain equidistance between the illuminated planes. Non-uniformities in the laser sheet and laser absorption in the flame are compensated for as the position-and time-dependent OH concentration is calculated throughout the measurement volume. A method for identifying the flame front in large data sets with a single set of filtering parameter is demonstrated. The artefacts introduced by the non-instantaneous recording of the measurement volume are suppressed using... (More)

A method for identifying the flame front in large data sets with a single set of filtering parameter is demonstrated. The artefacts introduced by the non-instantaneous recording of the measurement volume are suppressed using linear interpolation from successive recordings in the same measurement plane. The impact from filtering and image post-processing on the achieved spatial resolution is investigated. A final spatial and temporal resolution of 3.2 x 3.2 x 0.75 lines/mm and 2 ms, respectively, are obtained in a measurement volume spanning 11 x 22 x 6 mm during a time span of 0.5 s. (Less)
