Fluid-Structure Interaction: Modelling, Simulation and Applications
It is with my great regret that the FSI doctoral course will be cancelled this year. Due to my busy spring schedule, which was suddenly blown up by several new projects and teaching duties, I would have limited time for the course like last year. I believe that the course quality would be heavily influenced if I invest shorter time and energy in preparing lecture materials, reviewing reports and arranging individual discussions, etc. I am very sorry about the news. The course will come back next year (2023). In any case, you are very welcome to contact me for any FSI problems outside of the course.
Institute: Dept. Mechanics and Maritime Sciences (M2), Chalmers University of Technology
Course code: FMMS035
Number of credits: 7.5 hp
Level: doctoral education
Academic Year: 2023, March-June
Prerequisites: Fundamental fluid dynamics and solid mechanics, ideally with the knowledge in computational fluid/solid mechanics (CFD, FEM, etc.).
Enrollment cap: 15 students
This course will introduce theories and numerical techniques on fluid-structure interaction (FSI). Numerical tools for FSI modelling and simulation will be introduced and investigated. The characteristic physical mechanisms in an FSI scenario are strongly dependent on the material properties of the fluid and structure, their shapes and dimensions, and the boundary conditions. Consequently, FSI modelling and simulation methods are diverse in different applications. In this course, FSI scenarios will be categorized. A set of representative cases in these categories will be introduced and exercised. Students are expected to propose projects based on their needs and interests. For each project, a numerical solver will be specifically designed with respect to the features of the corresponding FSI model. Tools for constructing numerical solvers are not restricted. The tools that the students have on hand and use at work will be adopted. The students can freely choose commercial soft wares (e.g., ANSYS, Simcenter STAR-CCM+, LS-DYNA, NUMECA, Hexagon MSC Software, COMSOL) and open-source soft wares (e.g., OpenFOAM, nektar++, Elmer, Salome, FEniCS, LUMA, preCICE). The projects will be documented in the form of written reports. The reports will be peer-reviewed. At the end of the course, the students will present their respective projects and teach each other the techniques utilized the projects.
This course is offered for PhD students at Chalmers and other Swedish universities, as well as international students from other countries. The course is free of charge. It does not cover the costs for travel, accommodation, and food. Industrial participants are welcomed as well, but a charge for 20 000 SEK will be made.
