Abstract
Detailed understanding of turbulent combustion phenomena is very important to develop high efficiency combustors which contribute to resolve global environmental issues. Since turbulent combustion involves strong interactions between turbulence and combustion reactions, highly-sophisticated measurement techniques both for fluid motion and flames are required. For fluid velocity, state-in-art dual-plane stereoscopic particle image velocimetry (PIV) is shown and its importance in turbulent combustion researches is discussed. For flame measurements, advanced planar laser induced fluorescence (PLIF) techniques such as simultaneous CH-OH PLIF, double-pulsed CH PLIF and simultaneous dual-plane CH/single-plane OH PLIF are presented and investigations on local flame structure, global/local flame dynamics and three-dimensional flame structures are surveyed. Finally, current state and challenges of multi-dimensional/multi-variables laser diagnostics which consist of the advanced PLIF and color-based dual-plane stereoscopic PIV are presented.
