Course Description


Dynamics of Combustion Waves: From Flames to Detonations

Lecturer: Prof. Paul Clavin, Aix-Marseille Université
Course Length: 15 hours (Mon – Fri)
Objective: The purpose of this course is to present advances in the theory of unsteady combustion waves in premixed gases. 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 (flames and detonations). The lectures will then cover a large variety of phenomena : wrinkled and cellular flames, quasi-isobaric ignition, self-extinguishing flames, thermo-acoustic instabilities, turbulent flames, com-bustion noise, direct and spontaneous initiation of detonations, detonation quenching, 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.

Combustion Chemistry

Lecturer: Prof. Hai Wang, Stanford University
Course Length: 15 hours (Mon – Fri)
Objective: A discussion of the fundamental and application of combustion chemistry with topics ranging from a review of thermodynamics, thermochemical properties, group additivity, basic quantum and statistical mechanics, reaction mechanisms and modeling, transition state theory, Rice-Ramsperger-Kassel-Markus theory, to solution of the master equation of collision energy transfer. Topics of transport theory and properties include the Chapman-Enskog theory and its applications. Concepts and application of detailed kinetic modeling of laminar reacting flows will be discussed.

Quantitative Laser Diagnostics for Combustion Chemistry and Propulsion

Lecturer: Prof. Ronald K. Hanson, Stanford University
Course Length: 15 hours (Mon – Fri)
Objective: Fundamentals of laser absorption and laser-induced fluorescence in gases, including molecular spectroscopy and photophysics. Basics of shock tubes as a primary tool for studying combustion chemistry, including recent advances. Example state-of-the-art applications of species-specific sensing for shock tube kinetics studies, and multi-parameter sensing in different types of propulsion flows and engines.

Computational Turbulent Combustion

Lecturer: Dr. Thierry Poinsot, Institut de Mécanique desFluides de Toulouse, CNRS
Course Length: 15 hours (Mon – Fri)
Objective: This course will enable engineers and research specialists with knowledge of fluid mechanics to move to an integrated understanding of numerical combustion especially in the field of unsteady turbulent combustion. It will present basic techniques and recent progress in numerical combustion while establishing important connections with the underlying combustion basics. The course will include RANS, LES, and DNS modeling but also numerical methods adapted to these models. It will present and explore multiple examples of turbulent combustion and combustion instabilities in real combustors.
