Course Descriptions

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

Combustion Theory, Modeling, and Application

Lecturer: Professor Heinz Pitsch, RWTH Aachen University, Germany

Course Content: Fundamental knowledge in laminar and turbulent combustion, applications in CFD, machine learning and data analysis: laminar premixed and diffusion flame structure, flammability limits, laminar flame simulations using the FlameMaster code, introduction to turbulence, DNS and LES, turbulent combustion and modeling, CFD and numerical combustion with application to internal combustion engines and gas turbines. Focus topic: Hydrogen combustion.

Advanced Laser Diagnostics in Combustion Research

Lecturer: Professor Mark Linne, The University of Edinburgh, UK

Course Content: This course will introduce 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. A selection of diagnostics will be presented in the same context. Techniques to be discussed will include Rayleigh and Mie scattering, particle image velocimetry (PIV) and wavelet-based optical flow velocimetry (wOFV), ballistic imaging, structured laser illumination planar imaging (SLIPI), two-photon planar laser induced fluorescence in sprays, absorption-based techniques (e.g. frequency comb spectroscopy), laser induced fluorescence for combustion species, Raman scattering, and nonlinear optics including laser induced thermal acoustics and coherent anti-Stokes Raman scattering. A lecture on lasers and laser physics will also be provided.

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

Combustion Chemistry

Lecturer: Professor Alison Tomlin, University of Leeds, UK

Course Content: Chemical kinetic processes underlie all combustion phenomena. Consequently, accurately predicting chemical changes is fundamentally important for predicting combustion within a range of devices including engines, boilers, furnaces and gas turbines. On the other hand, chemical oxidation processes, particularly for complex fuels such as biofuels, involve very large numbers of species and reactions, posing challenges for including detailed chemistry within models of practical devices. With this in mind, the course will take students on a journey from the fundamentals of reaction kinetics basics through to constructing chemical mechanisms for different fuel types, reducing them to facilitate their use in reactive flow models and finally to quantifying the impact of inherent uncertainties on their predictive quality. Topics will include: chemical mechanism structure; stoichiometry; rate equations for basic reactors; temperature and pressure dependence of rate coefficients; determination of rate constants via experimental and theoretical methods; basic thermodynamics; automatic generation of reaction mechanisms; ignition phenomena and low temperature chemistry; adiabatic flame temperature and high temperature chemistry; pollutant formation mechanisms; future fuels and challenges they pose for combustion systems; model uncertainties and sensitivity analysis; chemical model reduction methods.

Combustion Dynamics and Unsteady Combustion

Lecturer: Prof. Sébastien M. Candel, CentraleSupélec, University Paris-Saclay, France

Course Content: This course provides an introduction to the analysis of combustion dynamics. After a broad introduction to acoustics and to early combustion instability models, the following topics will be covered: perturbed flame dynamics, flame transfer functions, nonlinear flame dynamics, flame describing function methods, the validity of these methods in instability analysis, premixed swirling flames and swirling spray flames, azimuthal coupling in annular combustors, passive and active control of instabilities. Questions of ignition and flame blow out will also be examined. The various concepts will be illustrated with experimental data, computational flame dynamics and large eddy simulations and many practical examples.

Note on Course Selection

The courses on Combustion Chemistry and Combustion Theory, Modeling, and Application are the foundational combustion courses, suggested to be taken by first-timers especially first-year students. The other two are advanced, enrichment courses.

Poster Session

Applicants are encouraged to submit abstracts for the poster session, with recently published or accepted papers by the presenter related to the work. Exhibition space is limited and decision on acceptance will be made by the organizing committee.

Note on Possible Rearrangement due to Covid-19

In the event of persistent inconvenience caused by Covid-19, the Summer School arrangement might need to be revised to various extent, such as off- instead of on-campus accommodation and the combination of on-site and remote lecturing. Every effort will be made to preserve classroom lecturing and promote networking.

Recognizing that changes in the arrangement could also affect the amount and the date of payment of the registration fee, updated information will be communicated to the registrants as well as posted on the website of the Summer School.
