Abstract

Simultaneous high-speed stereo-particle image velocimetry, OH planar-laser-induced fluorescence (PLIF), and ${{\rm{CH}}_2}{\rm{O}}$ PLIF measurements in a vitiated bluff body combustor are considered. An ex situ, simultaneous, time-resolved laser sheet intensity profile correction procedure is introduced. This procedure is easily implemented experimentally and is capable of correcting multiple sheets at the same time. As a proof of concept, the procedure is applied to perform correction of the ${{\rm{CH}}_2}{\rm{O}}$ PLIF images in vitiated and unvitiated conditions. The challenges associated with ${{\rm{CH}}_2}{\rm{O}}$ PLIF under these combustor operating conditions are also discussed.
