388-5000-00LComputational Fluid Dynamics for Non-Newtonian Flows Restricted registration - show details 3 credits2GF. Tanner, E. J. Windhab, K. Feigl
AbstractSolving 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.
Learning objectiveIntroduction 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.
Content1. 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
Lecture notesLecture notes will be provided.
Prerequisites / NoticeThe 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.

752-3022-00LFood Factory Planning and Design3 credits2GS. Padar, E. J. Windhab, P.  Beck
AbstractThe focus is directed on the interaction (and interdependency) of the different crafts involved, mainly construction, building services, and installation engineering. Hygienic requirements have to be designed and finally are implemented in order to achieve international standards (GMP, IFS, BRC). Insight is given into contract and payment handling.
Learning objectiveStudents learn about the tasks and responsibilities of the specialists (engineers, planners), organizations and distributors involved. Knowledge is provided on the coordination and guidance of people involved. An insight into hygienic and technical specifications as well as the regulatory framework is given. Finally, the implementation of a functional, ecological and cost efficient solution is discussed.
Lecture notesVorlesungsunterlagen (besprochene Folien, ca. 150 Seiten) werden an der ersten Vorlesung ausgegeben.
752-3024-00LHygienic Design2 credits2GJ. Hofmann, E. J. Windhab
AbstractThe lecture course Hygienic Design covers the special requirements in the design of equipment and components used in food production. Material science and surface treatments are as important as the cleaning mechanisms of these surfaces. Explanations of basic design requirements in food production areas, as well as the relevant regulations associated, are covered in this course.
Learning objectiveTo identify and evaluate hazards of food safety which can come from the equipment used in the food processing. Understanding of the most important design principles for easy cleaning of machinery and equipment.
