Course detail

Fluid Structure Interactions

FSI-RITAcad. year: 2019/2020

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.

Learning outcomes of the course unit

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.

Specification of controlled education, way of implementation and compensation for absences

Attendance at seminars and written tasks in the seminars.
