Course Description

 

Combustion Dynamics

Lecturer: Prof. Sébastien M. Candel, École Centrale Paris

Course Length: 15 hours (Mon – Fri)

Session: Morning Session

Objective: This course provides an introduction to the analysis of combustion dynamics problems. It includes a tutorial on acoustics and on early combustion instability models and deals with perturbed flame dynamics, flame transfer functions, nonlinear flame dynamics, flame describing function methods, swirling flames, spray flames, azimuthal coupling in annular combustors, passive and active control of instabilities. Concepts will be illustrated with experimental data and numerical simulations.

Chemical Kinetic Modeling for Combustion

Lecturer: Prof. Henry J. Curran, National University of Ireland, Galway
Course Length: 15 hours (Mon – Fri)

Session: Morning Session

Objective: This course provides an introduction to the development of detailed chemical kinetic mechanisms to describe the oxidation of hydrocarbon and oxygenated hydrocarbon fuels. It includes a tutorial on the importance of thermochemistry and the use of group additivity to estimate/calculate thermodynamic parameters for species using the THERM program. There will be a detailed discussion on the important general classes of reactions associated with fuel oxidation and the calculation/estimation of the important rate constants associated with these reactions. The importance of good experimental data which are used as validation targets will also be discussed.

Combustion Physics

Lecturer: Prof. Chung K. Law, Princeton University

Course Length: 15 hours (Mon – Fri)

Session: Afternoon Session

Objective: 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.

 

Advanced Laser Diagnostics in Combustion Research

Lecturer: Prof. Mark A. Linne, University of Edinburgh 

Course Length: 15 hours (Mon – Fri)

Session: Afternoon Session

Objective: This course will begin by introducing the basic topics underlying laser diagnostics; including development of commonly used expressions from the equation of radiative transfer, selected topics in physical optics, an introductory explanation of quantum mechanics and molecular structure, transitions, transition strengths and transition line shapes. Following that a selection of diagnostics is presented in the same context. Techniques to be discussed will include absorption, absorption tomography, cavity enhanced techniques, laser induced fluorescence, spontaneous Raman scattering, and new approaches to coherent anti-Stokes Raman spectroscopy. A lecture on laser physics will also be included.

Turbulent Combustion: Experiments and Fundamental Models

Lecturer: Prof. James F. Driscoll, University of Michigan
Course Length: 15 hours (Mon – Fri)

Session: Afternoon Session

Objective: Simple stretched flamelet ideas first are discussed to understand premixed turbulent flames, leading to the concepts of turbulent burning velocity and flame surface density. Modern ways to model and measure these quantities are reviewed for different regimes when broadened flamelets and distributed reactions occur. For non-premixed turbulent flames, recent measurements and models of mixture fraction and scalar dissipation rate are considered along with challenges for future research.
