Laser-induced incandescence in microgravity

Research output: Contribution to journalConference articlepeer-review


The elimination of buoyancy-induced convection in microgravity combustion processes, both flame shape and fv was different as compared to the same fuel/burner system in normal gravity. The sensitivity, temporal and spatial capabilities in addition to geometric versatility enabled laser-induced incandescence (LII) reveal the soot volume fraction regardless of these differences. Application of LII to laminar gas-jet flame of ethane illustrated the sensitivity of LII while application to turbulent diffusion flame of acetylene and vortex formed by a transient gas-jet diffusion flame of propane demonstrated the high temporal and spatial capabilities of LII for fv determination.
