Investigation of Rotating Turbulent Flows Using Large Eddy Simulations
Rotating turbulent flows which are common place in nature, are difficult to study numerically. The different regimes they may exhibit, and the wave interactions taking place in such flows necessitate high resolution and long time integration simulations to investigate them. Therefore, in order to reach high Reynolds and small Rossby numbers, modeling becomes a necessity.
I will present a Large Eddy Simulation model based on the Eddy Damped Quasi Normal Approximation that allows such simulations, and show comparisons to high resolution Direct Numerical Simulations as well as new results obtained on a parametric study using this model.
