Fundamental Processes
The topics within this group explore the general and foundational concepts in combustion that could be motivated by but need not directly relate to an application. The exploration is predominantly conducted in canonical configurations that expose the targeted processes:
-
Chemical kinetics, including the kinetics of hydrocarbons, oxygenated fuels, and alternative fuels, formation of gaseous pollutants and particulates, and elementary reactions
-
Flame dynamics and transport processes, including exploration of laminar flames and physics aspects of ignition, structure, propagation, extinction, dynamics, and instabilities
-
Turbulent flames, including exploration of high Reynolds numbers regimes in single and multiphase flames, and physics aspects relevant to ignition, structure, propagation, extinction, dynamics, and instabilities
-
Detonations and high-speed combustion, including fundamental principles governing compressible reactive flows, dynamic structural and stability issues in flame acceleration, and deflagration-to-detonation transition
-
Heterogeneous combustion and processes, pertaining to chemical and physical changes in two-phase reacting systems, such as those involving droplets, metal combustion, solid propellants, coal, biomass, waste conversion, and fundamental processes in fire
