KurzbeschreibungSolving inelastic non-Newtonian flow problems using finite volume techniques. Topics include an introduction to fluid dynamics, a discussion of non-Newtonian viscosity models, and a discussion of numerical issues, such as accuracy, convergence, and stability. Topics also include two-phase flow problems with moving interfaces, turbulence modeling, and spray modeling.
LernzielIntroduction to the foundations of Computational Fluid Dynamics (CFD) for non-Newtonian fluid systems. The course provides participants with theoretical background in CFD methods, discusses applications in various fields, and provides hands-on experience using CFD software via practical computer exercises.
Inhalt1. Tensor review and Fluid dynamics review
2. Rheology and constitutive equations for non-Newtonian systems
3. Boundary conditions including moving boundaries
4. Basic concepts of Finite Volume Method
5. Finite Volume Methods applied to flow problems
6. Introduction to the OpenFOAM CFD software package
7. Numerical issues such as convergence, stability and accuracy
8. Applications, e.g. multi-phase flows, turbulence and sprays
SkriptLecture notes will be provided.
Voraussetzungen / BesonderesThe course includes computer exercises using the open source software OpenFOAM. Participants are expected to have sufficient computer skills and access to a laptop for the in-class computer exercises.
