Course detail
Fluid Structure Interactions
FSI-RIT Acad. year: 2025/2026 Summer semester
The course familiarises students with the impact of different physical fields on moving stiff and elastic bodies (e.g. impact of liquid in journal bearings and sealing gaps on rotor dynamics, impact of gravitational and electromagnetic fields on rotor stability).
Generally, the effect of these fields on vibrating body is investigated.

Aims
The aim of the course is to acquaint the students with various force fields that have impacts on solid and elastic body. Also dealt with are the effects on the mechanical system characteristics. Another goal is to develop students´ creative thinking with respect to systematic conception of mechanics.
Students will have an over view of the effects of different types of surrounding with respect to the machine and device dynamics.
