Content
1.Energetic study of fuels and their use.
Origins and formation of fuels.
Conditioning and specification of fuels. Global mass and energy balance laws in combustion. Control and diagnostic techniques.
2. Thermochemistry.
Chemical kinetics of combustion. Chain-branching mechanisms. Explosivity and flammability limits, flame temperature. Chemical reaction rates. Pollutant formation. Measurement techniques.
 3. Combustion and heat transfer technologies.
 Laminar premixed flames. Introduction to turbulent flows. Turbulent premixed flames and their applications. Introduction to detonations.
4. Use of heat:
Heat transfer basics. Conduction, free and forced convection. Applications to combustion-related problems.
The balance laws of mass and of energy and the physico-chemical calculations are the objects of exercises and laboratory experiments. In these experiments emphasis is placed upon the phenomenology of combustion, control methods and diagnostics and upon operating methods
