Combustion Physics

The course is taught every second year; spring 2022, then next time spring 2024.
Thermodynamical basis, chemical kinetics, transport phenomena, fundamental equations and models for transport
of species and heat. Premixed and non-premixed flames. Turbulence and turbulent flames. Extinction and ignition. Formation of various desired or undesired chemical species (chemical products or pollutants) in chemical reactions. Combustion models for turbulent combustion. Individually designed special issues.

Knowledge:
The student gets insight into
chemical kinetics, chemical mechanisms
laminar and turbulent flames
the interaction between turbulence and chemical reaction; how this can be expressed mathematically
turbulence theory and modeling
flame regimes, small and large scales (time, length)
different combustion models; theoretical basis, underlying assumptions and usage

Skills:
The student should be able to
-understand the relations between flow and combustion.
-do simplified and detailed calculations for combustion.
-select models (turbulence, combustion, chemistry) for use with computational fluid dynamics (CFD).
-further work on special cases of combustion in the doctoral work.
-understand and work on a wide spectrum of combustion cases.
-transfer knowledge between different kinds of combustion cases.

General competence:
The student should have an understanding for
-that fluid mechanics, thermodynamics, heat and mass transfer and chemistry is generic knowledge.
-how to use the theory to solve new problems.
-how combustion works and how it can be changed, e.g., to reduce pollution and increase energy utilization.

Guided self study, colloquia. Excersises. To pass the course a score of at least 70 percent is required.
