Unit of study_
MECH5265: Combustion
This unit of study aims to teach the basic principles of combustion highlighting the role of chemical kinetics, fluid mechanics, and molecular transport in determining the structure of flames. Students will become familiar with laminar and turbulent combustion of gaseous and liquid fuels including the formation of pollutants. Students will also be briefly introduced to various applications such as internal combustion engines, gas turbines, and fires. This unit will cover equilibrium compositions, flammability limits, simple chemically reacting systems, detailed chemical kinetics, and the basic theory underlying laminar and turbulent combustion for both premixed and non-premixed cases. There will be an introduction to droplet and spray combustion, the concept of mixture fraction for non-premixed flames, combustion in engines and gas turbines as well as the formation of pollutants. New concepts for clean modern engines, with increasing reliance on renewable energy, are highlighted. Issues relating to buoyant fires and plumes, including fire suppression may also be covered.
