Abstract Details

2013, Master of Science, Ohio State University, Aero/Astro Engineering.
In the past few decades, Large eddy simulation has seen a surge in interest from the CFD community owing to its inherent advantages in terms of accuracy compared to RANS methods. Advances in computing power and memory capacity has now made it possible to use LES frequently, atleast at the academic level. The focus of the present work is to simulate a standard test case featuring ow separation, re- circulation, reattachment and observe how LES performs in comparison to RANS, since separated turbulent ow is one of the most challenging cases for any turbu- lence solver, especially for wall bounded ows. The major thrust of the work will be to implement a Dynamic Smagorinsky Subgrid Model proposed by Lilly (1992) in OpenFOAM and compare its accuracy with the standard Smagorinsky-Lilly model for the same case. Additionally, a considerable amount statistical analysis has been performed to better understand physical ow features from a statistical viewpoint and corroborate the results.
