Combustion Chemistry and Modeling
Lecturer: Dr. Charles K. Westbrook, Lawrence Livermore National Laboratories
Course Content:This course will describe simulations of combustion chemistry of conventional hydrocarbon and biomass-derived fuels, illustrated by examples from laboratory experiments and practical engines. Relationships between fuel molecular size and structure on rates of combustion will be emphasized. The concept of chain reactions will be used to explain autoignition problems and the concept of incomplete oxidation will be used to illustrate many types of chemical pollutant emissions. The use of reaction path analysis and how changing conditions, such as temperature, pressure, and fuel/air ratio,alter those reaction pathways will be another focus of these lectures.
Quantitative Laser Diagnostics for Combustion Chemistry and Propulsion
Lecturer: Prof. Ronald K. Hanson, Stanford University
Course Content:This course seeks to provide an introduction to optical spectroscopy and laser diagnostics relevant to combustion gases. Primary topics include rotational, vibrational and electronic spectra, theory of spectral lineshapes, and laser diagnostic techniques such as spectrally resolved absorption, laser-induced fluorescence and selected techniques based on light scattering. Example applications of laser spectroscopic diagnostics will be provided throughout, including measurements in various propulsion engines, energy conversion facilities such as coal-fired combustors and coal gasifiers, and in fundamental laboratory facilities such as shock tubes and flames.
Lecturer: Prof. Moshe Matalon, University of Illinois at Urbana-Champaign
Course Content:The aim of this course is to provide students with an understanding of the basic principles of combustion processes, how they relate to experimental observations and how they are used in theoretical and numerical modeling. The lectures will cover the fundamentals of chemically reacting flows, classification of combustion waves, the structure of deflagrations and detonations, hydrodynamics effects, ignition and extinction phenomena, flame instabilities, and aspects of multi-phase and turbulent combustion.
Computational Turbulent Combustion
Lecturer: Dr. Thierry Poinsot, Institut de Mécanique des Fluides de Toulouse, CNRS
Course Content:This course will enable engineers and research specialists with a knowledge of fluid mechanics to move to an understanding of numerical combustion especially in the field of unsteady turbulent combustion in real combustion chambers. 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 and discuss the major numerical differences between these approaches. It will present and explore multiple examples of turbulent combustion and combustion instabilities in real combustors. Ignition, quenching, flame-wall interaction, coupled radiation / heat transfer / flow computations, tabulation techniques for turbulent flames, bifurcations in real flames will also be discussed.
