Large Eddy Simulation of Turbulent Combustion: Theory, Modeling and Practice - NEW!

6–7 January 2018
0800-1700 hrs


The purpose of the course is to introduce the large eddy simulation (LES) approach to modeling complex reacting flows through three different elements: 1) Theory, 2) Modeling and 3) Practical implementation or practice. The first part will focus on the concept of filtering and associated mathematical and physical considerations. The second part will address the issue of subfilter modeling for a variety of combustion processes, and introduce the concept of dynamic modeling procedure for LES. The third part will consider practical issues in the implementation of LES models, including the effect of numerics on simulations and methodologies for mitigating these interactions.

Key Topics

  • Understand the main theoretical formulation of large eddy simulation
  • Understand the modeling requirements, common modeling approaches, and current state-of-the-art in combustion modeling
  • Understand the practical implementation considerations

Who Should Attend

The course is targeted towards everyone interested in advanced computational modeling of reacting flows. This includes industry researchers and CFD practitioners, AFRL and other national lab researchers, academic researchers including faculty, postdocs and students.

Course Instructor

Dr. Venkat Raman is a Professor in the Department of Aerospace Engineering at University of Michigan. His research interests include large eddy simulation, large-scale simulation of combustion systems, multiphase flows, scramjet and high-speed combustion, and uncertainty quantification.

Course Materials

Course notes will be made available about one week prior to the course event. You will receive an email with detailed instructions on how to access your course notes. Since these notes will not be distributed on site, AIAA and your course instructor highly recommend that you bring your computer with the course notes already downloaded.
