Course detail
Fluid Engineering
FSI-9FLI Acad. year: 2025/2026 Both semester
The course is focused on problems of theoretical and applied hydromechanics concerning the edsign of hydraulic machines and elements.
Basic equations of fluid mechanics are derived using the tensorial calculus. These equations are then applied to find new principles of hydraulic machines and elements.

Aims
Knowledge of the fluid flow and its interaction with rigid body applied to the design of hydraulic elements and mechanisms.
Students should carry out qualitative analysis of fluid flow and use it for design of fundamentally new systems which exploit the properties of fluid-structure interaction.
