Combustion Chemistry at Extreme Conditions
09:30 - 10:00
Level 0 lecture hall between Al-Jazri and Al-Kindi (buildings 4 and 5)
Insights into combustion chemistry can aid in improving energy generation systems. Knowledge of chemical kinetics and transport processes that govern combustion chemistry at extreme conditions is lacking. Fundamental chemical kinetic models with associated rate parameters and thermodynamics are needed for extremely high pressures, low temperatures, high dilution, and complex fuels. This presentation will cover the use of state-of-the-art comprehensive kinetic modeling tools together with high fidelity experimental measurements to study combustion chemistry at extreme conditions. First, we will cover traditional applications of improving fuel combustion in engines operating at high pressures and lean conditions. Next, kinetic processes of importance when burning at extremely high pressures of 300 bar and high CO2 dilution (e.g., Allam cycle) will be discussed. Finally, kinetic models for extremely complex heavy fuels under oxy-firing conditions will be addressed. The research draws upon expertise in quantum chemistry, fuel characterization, surrogate formulation, and chemical kinetic modeling.
