Fluid Mechanics and Hydraulic Components of a Nuclear Power Plant (FSI-LMJ)

The aim of the course is to acquaint students with the basic laws and theories of classical and modern fluid mechanics so that they are able to apply them to simple systems, clarify and predict their behavior. The challenge is for students to realize that fluid mechanics is the theoretical foundation of many engineering disciplines.

The subject allows students to gain knowledge about the properties of fluids, the balance of forces in fluids at rest, the movement of fluids in force fields, the basics of hydraulic machines and experimental methods. The student will learn to solve practical problems and create simplified models to study selected technical problems.

General knowledge of mathematics and physics at the level of completed courses at BUT. Basic knowledge of differential and integral calculus.

The subject is theoretically and practically focused on understanding the importance of hydraulic systems occurring in every industrial application. E.g. solving the flow in pipeline systems, choosing a suitable pump that will be able to ensure trouble-free operation of the equipment or designing the pipeline system so that its operation is safe and reliable. Students will learn to use not only the theoretical knowledge acquired in the previous study, but also to search for new necessary information.

Credit can be obtained based on the results of mandatory projects and participation in exercises.

The subsequent combined exam will be written, only in the case of the threshold number of points obtained, there will be an oral retest.
