Course Description

Lecture timeMorning (please select one of the following three courses)

Combustion Physics

Lecturer: Professor Chung K. Law    Princeton University

Course Content: This course presents combustion as a rigorous scientific discipline that is characterized by the canonical formulation of the theoretical foundation; the strong interplay between experiment, theory, and computation; and the description of combustion phenomena from the unified viewpoint of fluid mechanics and chemical kinetics. The course consists of three parts, namely: (1) the basic scientific components of chemical thermodynamics, chemical kinetics and transport phenomena; (2) the foundational concepts of premixed and diffusion flames, the limit phenomena of ignition, extinction and flame stabilization, and the aerodynamics of flames; (3) combustion in turbulent, boundary-layer, two-phase, and supersonic flows.

 

Fundamentals of Unsteady Combustion and Combustor Processes

Lecturer: Professor Tim C. Lieuwen   Georgia Institute of Technology

Course Content: This course will cover combustion fundamentals as applied to steady flowing combustion systems, such as burners, gas turbines, and boilers. It will particularly emphasize coupling between kinetic, flame aerodynamic, and fluid mechanics processes that control combustor behavior. The course will discuss pollutant emissions, with particular focus on NOx and CO emissions. Then, it will describe flame stretch processes, flame stabilization, and blowoff physics. It will discuss flame aerodynamics, inherent flame instabilities, and flashback. Finally, it will discuss thermoacoustic instabilities and flame-acoustic interaction processes.

 

Mechanism Reduction and Computational Flame Diagnostics

Lecturer: Professor Tianfeng Lu    University of Connecticut

Course Content: This course will provide an introduction to the methods for mechanism reduction based on graph theory, sensitivity analysis and timescale analyses, etc. Limiting factors for the efficiency of combustion simulations due to the use of detailed kinetics and possible solutions will be discussed.  Computational diagnostics based on chemical explosive mode analysis and bifurcation analysis will also be studied. The use of these diagnostics to capture critical flame features, such as ignition and extinction, will be demonstrated for laminar and turbulent flames.

Combustion Chemistry   

Lecturer: Professor Hai Wang   Stanford University

Course Content: Fundamental and application of combustion chemistry: thermodynamics, thermochemical properties, group additivity, basic quantum and statistical mechanics, reaction mechanisms and modeling, transition state theory, RRKM theory, master equation of collision energy transfer, Chapman-Enskog theory, concepts and application of detailed kinetic modeling of laminar reacting flows.

 

Dynamics of Combustion Waves in Premixed Gases

Lecturer: Professor Paul Clavin   Aix-Marseille Université

Course Content: The purpose of this course is to present advances in the theory of unsteady combustion waves in premixed gases; flames, detonations and explosions. Attention will be focused on fundamental aspects and the theoretical analyses will be developed in relation with carefully controlled experiments. The basic approximations of the conservation equations will be discussed first in the context of the structure of the planar waves. The lectures will then cover a large variety of phenomena occurring in many applied fields, ranging from safety in nuclear power plants to rocket or car engines: ignition, quenching, thermo-acoustic instabilities, cellular and turbulent flames, combustion noise, direct and spontaneous initiation of detonations, deflagration-to-detonation transition, Mach-stem formation on shock wave, galloping and cellular detonations. Each of these phenomena will be described by analytical solutions of the simplest model equations capturing the essential physical and chemical mechanisms.
