Combustion Summer School

Morning Sessions (please select one of the following two courses)

Combustion Chemistry and Modelling

Lecturer: Professor Henry J. Curran National University of Ireland, Galway, Ireland

Course Content:The 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.

Turbulent Combustion: Modelling and Applications

Lecturer: Professor Epaminondas Mastorakos University of Cambridge, UK

Course Content:Turbulent combustion sits at the intersection of chemistry and turbulence, both non-linear phenomena and both topics of extensive research. Modelling is needed in order to provide some predictive capability for this practically-important reacting flow problem. In these lectures, the usual models are reviewed, with focus on their theoretical justification and applicability to various situations showing finite-rate kinetic effects such as ignition, extinction, and pollutant formation. In addition to the theory, case studies from spark-ignition, diesel, and gas turbine engine combustion modelling are discussed extensively in order to show the strengths and limitations of each modelling approach. A brief overview of some pertinent topics from classical turbulence studies is included to enhance the student's understanding of turbulent combustion modelling.

Afternoon Sessions (please select one of the following two courses)

Combustion Theory

Lecturer: Professor Moshe Matalon University of Illinois at Urbana-Champaign, USA

Course Content:The aim of this course is to provide students with an understanding of the theoretical foundations of combustion science, and show how the acquired knowledge help assisting experimental and simulation studies and facilitate predictions of combustion systems. The focus will be on the physical aspects of combustion, associated with the fluid mechanics and transport and that will be presented in a systematic way, starting from the general equations describing the flow of chemically-reacting mixtures. Various approximations used in combustion studies will be discussed along with their physical significance. The topics presented include: deflagration and detonation waves, the planar premixed flame and the laminar flame speed, hydrodynamic theory of premixed flames, flame stretch and differential diffusion effects, the structure of detonation waves, diffusion flames, lifted flames and edge flames, ignition and extinction phenomena, burning of condensed fuels and spray combustion, intrinsic flame instabilities, and turbulent combustion.

Laser Diagnostics in Turbulent Combustion Research

Lecturer: Professor Jeffrey A. Sutton Ohio State University, USA

Course Content:The course provides an overview of several laser-based measurement techniques, building up from working principles to application. Velocimetry techniques, as well as scalar measurements for species concentrations and temperature will be discussed. Both particle-based and gas-phase measurements will be treated, focusing on the underlying light-matter interaction, spectroscopy, and signal interpretation. A primary area of discussion will target the challenges for quantitative measurements in turbulent combustion environments. Several high-fidelity measurement examples from laboratory-scale flames/reactors will be presented to showcase new insights to turbulent combustion physics. Finally, new and emerging laser-based approaches will be discussed which target a fully four-dimensional description of realistic combustion environments.
