Simultaneous high-speed stereo-particle image velocimetry, OH planar-laser-induced fluorescence (PLIF), and CH2O 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 easily implemented experimentally capable of correcting multiple sheets at the same time. As proof concept, applied to perform images unvitiated conditions. The challenges associated with under these...
Abstract This paper introduces a data-driven framework for combustor-focused, performance-based condition monitoring of gas turbines. Commercial systems typically generate huge amounts data that make efficient onboard challenging. focuses on quantifying combustor component degradation, using premixer centerbody degradation in swirl stabilized as case study. The input these analyses is acoustic pressure measurements acquired at various locations the combustor. diagnosis methodology based...
This work analyzes the dynamics of bluff body stabilized flames close to lean blowoff using simultaneous stereo-PIV (particle image velocimetry), OH PLIF (planar laser induced fluorescence) and CH2O PLIF. It is known that process occurs in at least two distinct stages: stage 1, where flame thought be riddled with extinction zones along front but otherwise appears similar a stable flame, 2, there large scale wake disruption flapping, which eventually leads complete blowoff. Little...
