Description:
Introduction to combustion processes; combustion thermodynamics, reaction kinetics and combustion transport. Chain reactions, ignition, quenching, and flammability limits, detonations, deflagrations, and flame stability. Introduction to turbulent premixed combustion. Applications in IC engines, furnaces, gas turbines, and rocket engines
Course Topics:
- Introduction to combustion processes; review of basic fluidmechanics: the derivation of mass, momentum and energy conservation equations based on the Reynolds transport theorem.
- Chemical thermodynamics, mixture fraction, the adiabatic flametemperature (the Burke-Schumann solution), chemical equilibrium reaction kinetics: the Arrehenius rate expression, the order of reaction, chain reactions (initiating, branching, propagating, breaking).
- Premixed combustion: Hugoniot relation (detonation, deflagration)the laminar flame structure, theoretical expression of the flame speed based on the Zeldovich theory, ignition, extinction and stability limits.
- Nonpremixed combustion: Stefan flow, droplet burning (governingequations and theoretical solution: mass consumption rate and flame location), counterflow combustion, flamelet transform.
- Combustion of nonvolatile fuels: coal combustion physics, carbon combustion at different limits, metal particle combustion, multi-component fuel combustion (miscible and immiscible cases), introduction of nitric oxides: formation mechanism of NOx and soot, engine combustion
- Combustion stability: acoustics physics, acoustics instability,acoustic energy, flame front instability and theoretical analysis
- Introduction to turbulent combustion
- Applications of combustion in engines (selective topic)
