Course detail
Fluid Engineering
FSI-9FLI Acad. year: 2019/2020 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.
