Large-Eddy Simulation of Turbulent Flows
(ME EN 7960-003) Fall 2014
will be based on a series of homework assignments and two course
projects. The grades in each of these categories will be
broken down as follows:
Approximately 3-4 homework assignments will be given during the semester. These assignments will focus on basic topics and ideas that will be needed in the projects (statistics of turbulence, filtering, power spectra estimation, model formulations, etc.). The assignments will be given throughout the semester when material is covered with an emphasis on the time period before the 1st project.
Project #1 (tentative):
Project #1 will focus on the application of LES SGS models in 3D turbulence simulations. Students will be provided a basic 3D numerical code which they will add their own SGS models to and will then examine the effect of base model type, model coefficient specification and grid resolution on the resolved simulated velocity fields. The project will be submitted in the form of a short report (~4 pages) outlining the basics of the simulation code used, the chosen SGS models and the results of parameter studies.
Project #2 will consist of gaining experience on doing a priori analysis of LES SGS models from experimental or numerical data. Data sets from various experimental setups (high speed turbulence sensors, PIV) or high resolution DNS will be provided for students to use in the projects based on the students research interests. Alternatively, if students have appropriate data sets (experimental or numerical) that they wish to use for their project they will be free to do so. The project will be submitted in the form of a short report (~4-6 pages) including: basics and background of the SGS models to be tested, a short description of the data set used in the analysis and a short summary of key results/incites gained from the tests. In addition to the project report, all students will be required to give a short presentation (~15 minutes) during the last weeks of class.
