Fluids are flowing everywhere: wind around turbines, buildings and mountains; water in rivers and oceans; gas in pipes and engines; in reactors; as blood in our vessels; in biological cells; and many more examples. The goal of this course is to provide an introduction to the use of commercial computational fluid mechanics (CFD) codes to analyze transport problems of practical interest to science and engineering. The emphasis of this project course is on the usage of CFD as a virtual fluid laboratory and it will provide hands-on experiences with CFD by studying a variety of flow situations related to process engineering, chemistry, nano- and biotechnology. You will get insights in the major difficulties in performing CFD computations with good quality and trust and the importance of experiences in basic fluid mechanics phenomena. The complete process from assumptions and simplifications, geometry development, mesh design, computation and analysing the results will be covered for both pure fluid mechanics problem and multiphysics problems.
At the end of the course students will understand the process of developing a geometrical model of the flow, applying appropriate boundary conditions, specifying solution parameters, and visualizing the results. They will also have an appreciation for the factors limiting the accuracy of CFD solutions. The course is also intended as an extension of courses on the theoretical foundation of fluid dynamics.
The generation of complex geometries using computer aided design (CAD) models or from the processing of 3D images acquired using modalities like confocal microscopy, MRI, or CT. Delaunay triangulations and tetrahedrizations, triangle and tetrahedron meshes, combinational topology, surface simplifications. Hierarchical models by using multiple geometries or combined mesh elements for geometries with large aspect ratios. Adaptive models. Multiphysics models. Model verification. Transport and reaction phenomena.
Solve one selected industrial or research problem in a project group of max three students. This includes to define and perform a complete CFD analysis, analyse the quality and trust in the results and to do some parametric study. The project will be reported and presented at a seminar in the end of the course.

The goal of the course is to get a solid understanding of basic fluid flows, its equations and analytical solutions, as well as its diverse applications. The course is divided into teaching sessions (34 %) and problem sessions (66 %).

Upon completion of the course, the student is expected to be able to:
The project work is documented by a written project report and by a presentation at the project seminar at the end of the course. The hard copy report should be handed in at the seminar. The project seminar is mandatory and during the presentation all project members must be present and be prepared to answer questions on all aspects of the work. Additionally, students should show that they have accomplished two or more of the course assignments by parametric studies, quality assessment or other additional values.
Students are expected to turn in laboratory assignment and homework problems that are substantially the result of their own work. Study groups, discussion of assignments among students, collective brainstorming for solutions, and sharing of advice is encouraged. Copying of assignments, computer files, graphs, or other means of duplicating material that is turned in for grading is expressly forbidden.
The final report and presentation forms the basis of the assessment, which is evaluated according to the 7- level scale, internal marking
