Title Laser Diagnostics Study of Plasma Assisted Combustion for Scramjet Applications.
Publication Date Dec 2011
Media Count 31p
Personal Author T. Lee
Abstract The main goal of this study is to apply advanced laser imaging and optical diagnostics to study the physicochemical impact of nonequilibrium plasmas to enhance the conversion of chemical energy in combustion, and to investigate new efficient concepts for coupling plasma energy into a flame, seeking future potential application in high speed engines including scramjets. Three separate topics have been investigated within the scope of this objective. The first topic involves quantitative planar laser-induced fluorescence (PLIF) imaging of nitric oxide (NO) in a transient arc DC plasmatron torch using premixed air/fuel mixtures.The second topic is the investigation of a novel concept of coupling the plasma energy directly into the reaction zone of the combustion (Direct Coupling). The final topic involves the study of direct plasma coupled flames in more practical geometries for both premixed and non-premixed conditions.
