Why is it useful to study combustion? One motivation is that this source contributes with more than 85% of all the energy supply in the world, and the energy usage increase globally by 3% per year. Another motivation is that knowledge in combustion is important for the modern engineer to be able to make combustion processes more efficient and to develop them to produce less pollutants, such as hydrocarbons, particles and nitrogen oxides. Thus, we need to study combustion processes. Research on alternative fuels also enables a transition to a future sustainable society.
This course aims at providing the basics for understanding combustion phenomena. This includes thermodynamics, chemical kinetics, ignition, fluid dynamics and the formation of pollutants. From the knowledge in these areas it is possible to reach an understanding for energy related and environmental problems connected to real life combustion.
