FSI-9FLIAcad. year: 2020/2021
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.
Learning outcomes of the course unit
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.
Mechanics of rigid and elastic bodies.
Differential and integral calculus.
