FUNDAMENTAL COMBUSTION

FBR012

Higher education credits: 7,5. Grading scale: TH. Level: G2 (First level). Language of instruction: The course will be given in English on demand. Optional for: F3, F3fs, M4, M3fs, W4. Course coordinator: Per-Erik Bengtsson, per-erik.bengtsson@forbrf.lth.se, Fysik, kurslaboratoriet. Recommended prerequisits: FMF150 Thermodynamics and Statistical Physics, KFK080 Thermodynamics, MMV201 Applied Thermodynamics, Basic Course, FFF100 Thermodynamics and Electronical Materials. Assessment: To pass the course the student must pass the written examination, the laboratory exercises, the compulsory exercises, and the project. The grade is weighted from the project (1/3), and the examination (2/3). Compulsory exercises that have been well performed give additional points on the examination.

Aim
The aim of the course is to provide a fundamental understanding for the physical processes in combustion. Important areas are thermodynamics, chemical kinetics, radiation, transport processes. From this basic understanding combustion phenomena and systems can be analysed such as autoignition, flame propagation, extinction, and pollutant formation. Improved understanding of combustion processes is highly important to improve efficiency and decrease harmful emissions, which is of global importance since 90% of the energy usage in the world can be related to combustion processes.

Knowledge and understanding
For a passing grade the student must

be able to explain how thermodynamics, chemical kinetics, radiation, and transport processes lead to different characteristics for combustion processes.
be able to describe the physical processes taking place for different combustion phenomena and in practical combustion systems.

Skills and abilities
For a passing grade the student must

be able to analyse a combustion process with regard to efficiency and pollutants
be able to calculate parameters such as temperature and species concentrations from thermochemical data of a combustion system.
be able to write reports from laboratory exercises with analysis of measurement data and discussion about uncertainties
be able to write a project report on a topic in the combustion area and present it orally.
be able to assimilate the important information in scientific papers of more bascis character and in an advanced English text book.
be able to solve problems with help from other sources than the course material, for example previous courses within the laser/optics area.

Contents
Introduction, thermochemistry, chemical equilibrium, adiabatic flame temperature, chemical kinetics, ignition processes, combustion physics, premixed and diffusion flames, turbulent combustion, pollutant formation, combustion diagnostics, and practical combustion systems.

Laboratory exercises: 1) Computer simulations of self-ignition and flame propagation, 2) Measureemnts of flame velocities and demonstrations of different methods for combustion diagnostics

Project: Subject is chosen after discussion with teacher. After the study, it is summarised in a written report and presented orally.
