Students are expected to master the following skills: fundamentals of thermodynamics and of fluid mechanics, as they are covered within the courses LMECA1855 and LMECA1321.
Origins, nature, and conditioning of fuels. Mass and energy balance laws of combustion. Physical chemistry and chemical kinetics of combustion: reacting schemes and phenomenology of the modes of combustion. Fuel combustion technologies: conception and design of combustion heat transfer equipment.
With respect to the reference AA of the programme of studies "Masters degree in Mechanical Engineering", this course contributes to the development and acquisition of the following skills
- AA1.1, AA1.2, AA1.3
- AA2.3, AA2.4, AA2.5
- AA3.1, AA3.3
- AA4.1, AA4.2, AA4.3, AA4.4
- AA5.2, AA5.4, AA5.5
- AA6.1, AA6.4
Specific learning outcomes of the course
To provide the theoretical and practical background in the use of fuels via a physico-chemical approach to combustion and to present the technological aspects relative to fuel combustion.

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
