AIMS AND CONTENT

LEARNING OUTCOMES

The course provides the basic knowledge on combustion theoretical modeling and diagnostic techniques, and the applied know-how relevant for engineering applications.

AIMS AND LEARNING OUTCOMES

At the end of the course the student will be able

- to understand the physical aspects of the combustion and their influence on flame size, stability and ignition;

- to know and apply simple combustion models for premixed and diffusion flames of gas, liquid droplets and solid particles;

- to discuss the requirements of the combustors for aeronautical applications and to identify appropriate design solutions;

- to understand the background physics and the implementation problems of the optical techniques for combustion diagnostics;

- to analyse experimental and numerical results in combustors

TEACHING METHODS

Theoretical and applied lectures: presentation and discussion of the theoretical contents, experimental and numerical results.

SYLLABUS/CONTENT

Principles of combustion, theoretical models and experimental data: detonation waves; premixed laminar and turbulent flames; ignition; flame stabilization; laminar and turbulent gaseous diffusion flames; combustion of a single liquid fuel droplet; atomization and sprays; burning of solids.

Optical techniques for combustion diagnostics: background physics; application fields and experimental considerations; spray diagnostics; applied combustion diagnostics in internal combustion engines and gas turbines.

Gas turbine combustors: design technology trends; fuel injection systems; flame stabilization; ignition performance; afterburners; low-emissions combustors.
