Message for students
Flow-induced vibrations are important engineering problem and measures have been taken in many machines and plants. In this lecture, complex problems on flow-induced vibrations are modeled as simple mathematical models. I hope that you will enjoy mathematical modeling of fluid-structure interaction problems.
