Flame Dynamics and Chemistry in LRE Combustion Instability
Abstract
This proposal offers to study liquid rocket engine instability mechanisms, especially at the downstream of the fuel injection nozzle where a complex flame structure exist. Since injection of fuel and oxidizer is the source of energy input, dynamics of nozzle injection and the subsequent fuel-oxidizer mixing and combustion plays important role in the combustion instabilities. This study aims to understand premixed combustion at the flame stabilization region that consists of a triple flame structure at the base, premixed flame segment, diffusion flame structure with left over reactants, and the effects of the chemical kinetics on this complex structure. Study will also investigate auto-ignition in a turbulent flow, diffusion flamelet effects, intrinsic flamefront instabilities, and the role of vortices.
