AbstractParticipants will learn to use the open source simulation software OpenFOAM on a user level (i.e. to conduct classical CFD studies). We will also introduce the students into programming with OpenFOAM so they will be able to implement additional equations into existing solvers.
ObjectiveParticipants will learn to use the open source simulation software OpenFOAM on a user level (i.e. to conduct classical CFD studies). We will also introduce the students into programming with OpenFOAM so they will be able to implement additional equations into existing solvers.
ContentOpenFOAM is a very professional open-source simulation package which is freely (CHF 0.-) available under the GNU General Public License (GPL). It consists of a vast C++ library, many different applications and additional tools. Although most of the existing applications are flow solvers, OpenFOAM can be used in many different areas, as varied as solid dynamics, electromagnetics or pricing of financial options.

Most users make only use of the included applications. One particular strength of OpenFOAM, however, is that new applications and even extensions of the library can be developed in a rather compact and elegant way.

151-0212-00LAdvanced CFD Methods Information 4 credits2V + 1UP. Jenny, D. Lakehal
AbstractFundamental and advanced numerical methods used in commercial and open-source CFD codes will be explained. Topics include incompressible and compressible Navier-Stokes solvers, gridding, immersed boundary methods, source terms, front tracking, flow coupled with heat and mass transfer and multi-phase flow with phase change. For some of the exercises a commercial CFD code will be employed.
ObjectiveKnowing what's behind a state-of-the-art CFD code is not only important for developers, but also for users in order to achieve meaningful and accurate numerical results. To acquire this knowledge is the main goal of this course, which consists of two parts.

Part 1 deals with established numerical methods to solve the incompressible and compressible Navier-Stokes equations, whereas the focus lies on finite volume methods for compressible flow simulations. In that context, first the main theory and then numerical schemes related to hyperbolic conservation laws are explained, whereas not only examples from fluid mechanics, but also simpler, yet illustrative ones are considered (e.g. Burgers and traffic flow equations).

In Part 2, some advanced CFD topics are covered with strong emphasis on hands-on experience with a commercial CFD solver. Topics include, gridding, immersed boundary methods, source terms, Lagrangian and Eulerian front tracking, flow coupled with heat and mass transfer and multi-phase flow with phase change.
ContentFundamental Topics
- Finite-difference vs. finite-element vs. finite-volume methods
- Basic approach to simulate incompressible flows
- Brief introduction to turbulence modeling
- Theory and numerical methods for compressible flow simulations

Advanced Topics
- Gridding
- Immersed boundary methods
- Source terms
- Lagrangian and Eulerian front tracking
- Flow with heat and mass transfer
- Multi-phase flow with phase change
Lecture notesPart of the course is based on the referenced books. In addition, we hand out a manuscript and slides, which contain not all the course material, however.

151-0980-00LBiofluiddynamics4 credits2V + 1UD. Obrist, P. Jenny
AbstractIntroduction to the fluid dynamics of the human body and the modeling of physiological flow processes (biomedical fluid dynamics).
ObjectiveA basic understanding of fluid dynamical processes in the human body. Knowledge of the basic concepts of fluid dynamics and the ability to apply these concepts appropriately.
ContentThis lecture is an introduction to the fluid dynamics of the human body (biomedical fluid dynamics). For selected topics of human physiology, we introduce fundamental concepts of fluid dynamics (e.g., creeping flow, incompressible flow, flow in porous media, flow with particles, fluid-structure interaction) and use them to model physiological flow processes. The list of studied topics includes the cardiovascular system and related diseases, blood rheology, microcirculation, respiratory fluid dynamics and fluid dynamics of the inner ear.
Lecture notesLecture notes are provided electronically.
LiteratureA list of books on selected topics of biofluiddynamics can be found on the course web page.
