Prerequisites
It is expected that the students have mastered the basics of thermodynamics, as covered in the courses LMECA1855 or  LPHYS1343, as well as the basics of fluid mechanics, as covered in the courses LMECA1321 or LPHY1213.
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.
Learning outcomes

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
  • 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
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.
 
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
Teaching methods
  • Course lectures
  • Session of exercises
  • Laboratory: Operation of a domestic natural-gas boiler and analysis of its combustion efficiency.
  • Lectures in the classroom with physical presence
Evaluation methods
  • i) written exam, with open books and notes, and ii) laboratory report.
  • The score on the written exam counts for 75% of the overall grade. The score on the laboratory report counts for 25% of the overall score.
  • We maintain the right to ask a student for an oral exam in case of technical problems or suspicion of fraude.
