Title: Large Eddy Simulation of Mixing Layers
Authors: Lotfi, Amin
Abstract: Mixing layers have numerous applications and are of importance in investigations about transition, turbulence and the behavior of different flows in mixing process. Therefore, inquiries about various setups of mixing layers are pretty beneficial. Planar mixing layers are a subset of this subject which are implemented in applications such as combustion furnaces, chemical lasers, the lip of an intake valve in an internal combustion engine and the trailing edge of a turbine blade. Understanding the details of mixing area is critical in terms of chemically reacting and combustion mixing flows. Here in this project, an investigation on the planar mixing layers in transition to turbulence is carried out both in 2D and 3D. Effects of the splitter plate’s trailing edge on the growth of the shear layer is investigated through simulations with different thicknesses of the splitter. Finally, use of an alternative turbulence model (WALE) as a substitute for Smagorinsky model with constant coefficient is put into consideration.
