DESCRIPTION:Dr. Bruno Coriton\, Combustion Research Facility\, Sandia Nati
 onal Laboratories\, Livermore\, CA\nCombustion is the workhorse of our ene
 rgy and transportation industries and will continue to play an important r
 ole in the global economy for the foreseeable future. In light of increase
 d concern with fossil fuel supplies and pollutant emissions\, significant 
 fundamental research advances toward  the  development  of clean\, high
 ly-efficient and fuel-flexible technologies are essential. Practical combu
 stion devices operate under turbulent conditions. By studying the interpla
 y between turbulence and flame chemistry\, my research addresses the confl
 icting requirements of low-emission\, high efficiency schemes with high co
 mbustion stability. My research approach is to design and study compact\, 
 well-characterized laboratory flames\, featuring key turbulent combustion 
 dynamics encountered in more complex combustion systems such as engines\, 
 and to apply advanced laser-based diagnostics for quantitative analysis of
  important phenomena involved in these flames.\nIntense turbulence – fla
 me interactions can result in frequent localized extinctions that negative
 ly impact the stability\, efficiency and pollutant emissions of a combusti
 on system. Understanding and predicting the conditions leading to frequent
  local flame extinctions are therefore key to the design of practical comb
 ustion devices. First\, I will discuss how Laser Induced Fluorescence (LIF
 ) imaging of CO\, OH and CH2O was employed to probe the turbulent flame st
 ructure\, key reaction rates and  extinctions in  turbulent premixed  f
 lames exposed to mixing with hot combustion products. Although it is not a
 ccounted for in the standard theoretical framework\, flame mixing with com
 bustion products\, as encountered in practical combustion devices\, affect
 s the flame stability and frequency of localized extinctions. Second\, I w
 ill show how recent developments using simultaneous high-speed\, Tomograph
 ic Particle Image Velocimetry (TPIV) and OH LIF can be used to study the d
 ynamics of localized extinctions in turbulent flames. High-speed laser dia
 gnostic techniques have the potential to unveil entirely new insights into
  turbulent combustion dynamics.\nBio: Dr. Bruno Coriton’s research aims 
 to develop improved combustion processes and technologies for energy produ
 ction and transportation. He is a postdoctoral fellow in the Advanced Imag
 ing Lab at the Combustion Research Facility of Sandia National Laboratorie
 s in California. He received his Ph.D. degree in Mechanical Engineering fr
 om Yale University and his B.S. degree in Aeronautical and Mechanical Engi
 neering from l’Ecole Nationale Supérieure de Mécanique et d’Aérotec
 hnique (ENSMA) in France.
