Fluid Structure Interactions (FSI-RIT)

Academic year 2023/2024
Supervisor: prof. Ing. František Pochylý, CSc.  
Supervising institute: EÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
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.
Learning outcomes and competences:
Students will have an over view of the effects of different types of surrounding with respect to the machine and device dynamics.
Prerequisites:
Basics of hydrodynamics, thermomechanics and the body dynamics.
Course contents:
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.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:
Course-unit grade credit
Controlled participation in lessons:
Attendance at seminars and written tasks in the seminars.
Type of course unit:
    Lecture  13 × 2 hrs. optionally                  
    Exercise  13 × 1 hrs. compulsory                  
Course curriculum:
    Lecture Conception of macroscopic element. The Euler and Lagrange continuum theory. The motion equation of macroscopic element. The weight conservation law of macroscopic element. The additional effect of the liquid on the body. The magnetic field impact on the body. The through flow pipeline stability. The round flow body stability.
    Exercise The Buckingham II - theorem - the numbers of similarity. The Karman vortex effect on the constructions. Additional mass of various body - calculation methods. The through flow pipeline stability, the stability criteria. The pressure pulsation in a pipeline system, stiffness and inner damping effects of the pipe on the pressure pulsation amplitude. The fluid additive effect applications on the vertical pump.
