In this course, firstly the basic physics of combustion is lectured from the viewpoint of thermal dynamics and chemistry. Secondly, the mechanisms and characteristics in a variety of combustion processes, such as premixed flame and non-premixed flame, are presented．Thirdly, modeling of turbulent combustion and measurement techniques for combustion phenomena are studied.
Combustion phenomena is a basic physics of thermal-energy conversion system and is also related to a lot of engineering challenging fields such as chemical plants, waste treatments and fire accidents. Students will comprehensively understand fundamental mechanisms of combustion phenomena from the viewpoint of thermodynamics and chemistry, and learn computational and experimental methodologies for investigations of combustion systems.
By the end of this course, students will be able to:
1) Explain basic classification and characteristics of combustion phenomena in practical combustors.
2) Choose combustion model in numerical simulations to the porpose of investigations
3) Explain physical properties monitored or investigated for combustion system design and control, and measurement methods of the physical properties.

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
Materials will be provided if they are required.
