Simultaneous multiple laser beam intensity profile correction and its application to a vitiated bluff body combustor field
Abstract
Simultaneous high-speed stereo-particle image velocimetry, OH planar-laser-induced fluorescence (PLIF), and C H 2 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 C H 2 O PLIF images in vitiated and unvitiated conditions. The challenges associated with C H 2 O PLIF under these combustor operating conditions are also discussed.
