CFD for Combustion Modeling
The objective of the course is to provide the interested combustion engineer or researcher with the fundamentals of combustion modeling to assess a combustion problem and to decide on the adequate models to be used in numerical simulations. The course is designed to also provide the knowledge to implement certain models into CFD codes. The course starts with fundamentals of combustion chemistry and includes a hands-on introduction to a 0D/1D combustion code. This is followed by a brief introduction to statistical models and turbulence modeling. A comparative overview of the most commonly used combustion models will be given next. Implementation issues and application examples will be discussed. Special topics include combustion instabilities, combustion in aircraft engines, augmentors, and high-speed combustion.
- CFD for Turbulence
- Chemical Kinetics Modeling
- CFD approaches for Turbulent Combustion
- Modeling for Turbulent Combustion
- Emission and Instability Modeling
- Application to Gas Turbines, Augmentors and Scramjets

Since course notes will not be distributed onsite, AIAA and your course instructor highly recommend that you bring your computer with the course notes already downloaded to the course.
Once you have registered for the course, these course notes are available about two weeks prior to the course event, and remain available to you in perpetuity.
Professor Heinz Pitsch’s work is in computational energy sciences and includes modeling of combustion processes using large-eddy simulation, combustion chemistry and chemistry reduction for transportation fuel surrogates, soot formation, and modeling of liquid atomization and sprays with application to gas turbine engines, furnaces, and internal combustion engines. He works also on electrocatalysis and transport in porous media with application to fuel cells.
Professor Suresh Menon’s area of expertise is in large-eddy simulation of turbulent non-reacting and reacting flows. He has developed unique simulation capabilities to study turbulent mixing and combustion in gaseous and liquid-fueled gas turbine and rocket motors, as well as for ramjet/scramjet engines.
