Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

Main themes
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.
Aims
At the end of this learning unit, the student is able to : | |
| 1 |
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
More specifically, by the end of the course, the student will be able i) to apply the main concepts of the thermo-chemistry of combustion to the evaluation of the quality of combustion in energy systems, including thermal engines. ii) to perform calculations of combustion equipment and associated heat-transfer devices. iii) to understand the environmental aspects of fossil fuel combustion. |
The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.
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 of combustion.
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. Use of heat generated by combustion. Introduction to detonations
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
