Course Content
Scope of combustion. Combustion Thermodynamics. Basic transport phenomena. Chemical kinetics; reaction rate. Laminar and turbulent flames. Structure of detonation. Diffusion flames; liquid droplet combustion. Theory of thermal ignition. Pollutant formation.
Objectives of the Course
The aim of this course is to teach burning concept and problem solving methods in engineering. The course includes combustion conservation equations, thermochemistry, mass transfer, chemical kinetics, simplified analytical methods and solution of combustion problems by finite volume methods. Drip evaporation and combustion, laminar and turbulent premixed flames and diffusion flames (burning jets) will be examined. Students are required to have knowledge of fluid mechanics and heat transfer at undergraduate level. Mathematical models of engineering combustion problems are aimed to be solved by analytical and numerical methods.
