151-0114-00LTurbulence ModelingW4 credits2V + 1UP. Jenny
AbstractIn the study of turbulent flows the objective is to obtain a tractable quantitative theory or model to calculate quantities of interest. A century of expertise has shown the 'turbulence problem' to be notoriously difficult, and there are no prospects of a simple analytic theory. In this class, five of the leading computational approaches to turbulent flows are described and examined.
ObjectiveThe goal of this class is to give an good overview of current turbulence modeling approaches, but also to help developing a feeling for advantages and limitations of the various classes of models.
Content1. Introduction to Modeling:
The goal here is to present an overview of different approaches,
point out the main challenges and discuss general criteria for turbulence models
2. Direct Numerical Simulation (DNS):
After the basics of DNS are introduced, applications to homogeneous and
inhomogeneous turbulent flows are discussed.
3. Turbulent-Viscosity Models:
The implications due to the underlying assumption, the turbulent viscosity
hypothesis, are explained and discussed. Then, specific models belonging to the
classes of algebraic, one-equation and two-equation models are introduced.
4. Reynolds-Stress Models:
After a brief discussion of the concept and the advantage above
turbulent-viscosity models, most of the time will be spent for "return-to-isotropy
models, near-wall treatments and algebraic stress models.
5. Probability Density Function (PDF) Methods:
This part is at the center of this class. First, the concept of PDF modeling
is explained and the PDF transport equation is derived, discussed and analyzed.
It is shown that turbulent transport and reaction source terms appear in closed
form. However, models are required to close other terms. Then, consistent
Lagrangean models are presented. Using these equations and models, corresponding
Reynolds-stress models are derived. It is demonstrated how the PDF transport
equation can be used to analyze turbulent flows, even without using the PDF approach
for simulations.
6. Large-Eddy Simulation (LES)
The basic concepts of LES are introduced. After a discussion of filtering, the filtered
conservation equations are derived. As an example of a sub-grid model the
Smagorinsky model is presented and finally the perspectives of LES are discussed.
Lecture notesThe course is partly based on part two of the book "Turbulent Flows" by Stephen B. Pope published by Cambridge University Press, 2000. In addition, we hand out a manuscript, which contains not all the course material, however.

AbstractIntroduction to flow stability, bifurcation and transition to turbulence. Linear stability theory of parallel shear flows including inviscid and viscous instabilities. Concepts of temporal/spatial, local/global, absolute/convective instabilities. Stability results and transition mechanisms for specific flows, such as free shear, channel, boundary-layer and stratified flows.
ObjectiveA basic understanding of the primary concepts of hydrodynamic stability and transition to turbulence. Knowledge of stability results and transition processes in several standard flows such as free shear, boundary layer and stratified flows. Ability to apply the basic mathematical framework of linear stability theory.
ContentThis course gives an introduction to the most relevant instability mechanisms and transition processes in incompressible flows. Starting with the basic framework of linear stability theory, we will discuss the stability of several flow configurations of increasing complexity, e.g. free shear flows, 2D and 3D boundary layers and stratified flows. We will introduce the basic mathematical concepts and derive important theoretical results (Rayleigh and Orr-Sommerfeld equations, stability charts). The discussion of linear stability will be followed by a consideration of the laminar-turbulent transition process for selected flows. Different transition scenarios will be studied for technically relevant flows.

AbstractIntroduction to basic and advanced concepts of modern feedback control.
ObjectiveIntroduction to basic and advanced concepts of modern feedback control.
ContentThis course is designed as a direct continuation of the course "Regelsysteme" (Control Systems). The primary goal is to further familiarize students with various dynamic phenomena and their implications for the analysis and design of feedback controllers. Simplifying assumptions on the underlying plant that were made in the course "Regelsysteme" are relaxed, and advanced concepts and techniques that allow the treatment of typical industrial control problems are presented. Topics include control of systems with multiple inputs and outputs, control of uncertain systems (robustness issues), limits of achievable performance, and controller implementation issues.
