Course
Objectives:
- Become familiar with
the filtering concept in a turbulent flow and
how the idea of scale separation forms the basis
for LES.
- Gain familiarity with the
filtered forms of the conservation equations (e.g., mass,
momentum, turbulent kinetic energy), how they are derived
and how the different terms in the equations can be
interpreted.
- Obtain a basic working
knowledge of common subgrid-scale (SGS) parameterizations
used in LES of turbulent flows.
- Understand how to carry out a
priori analysis of SGS models from
experimental and Direct
Numerical Simulation
(DNS) data sets.
- Understand common techniques
for a posteriori
evaluation of SGS models and what conditions are necessary
and sufficient for a 'good' SGS model.
- Become familiar with LES SGS
models and techniques used in specific flow cases of
interest (e.g., isotropic turbulence, high-Reynolds number
boundary layers, turbulent reacting flows, etc.)
