Aims of the course unit: | ||||
Project, optimize and improve the creative thought of students in the hydraulic and pneumatic devices design. | ||||
Learning outcomes and competences: | ||||
The knowledge of applied hydrodynamics and the basic hydraulic elements and mechanisms principle. | ||||
Prerequisites: | ||||
Basics in hydrodynamics, thermo mechanics and the body dynamics | ||||
Course contents: | ||||
This subject is a continuation of the subject Fluid Engineering. The aim is deepening the knowledge abot unsteady motion of stiff and elastic bodies in real fluid. Intention is application on design of hydraulic elements and systems. | ||||
Teaching methods and criteria: | ||||
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work. | ||||
Assesment methods and criteria linked to learning outcomes: | ||||
Credit and Examination (oral exam) | ||||
Controlled participation in lessons: | ||||
Seminars and written tasks on the excercises | ||||
Type of course unit: | ||||
Lecture | 13 × 2 hrs. | optionally | ||
Labs and studios | 13 × 1 hrs. | compulsory | ||
Course curriculum: | ||||
Lecture | Unsteady motion of stiff body in real fluid. Application on motion of piston and valve. Principle of dynamic damper. Principle of hydrodynamic damper of rotor systems – tensor of aadded mass, stiffness and damping. Principle of hydrodynamic bearing – influence of compressibility and cavitation. Principle of hydrodynamic sealing gap for laminar and turbulent flows. Stiffness of liquid layer with Taylor vortices. Stability of pipe with through flow. Spectral and modal properties of compressible fluid – application on defect detection in pipeline system – searching for the accident based on pressure wave spreading. |
|||
Labs and studios | Computation of piston added mass in cylinder filled with liquid – design of dynamic damper of fluid system. Computation of added effects of fluid on rotor with hydrodynamic damper and journal bearing. Selfexcited valve vibration circumflowed by liquid. Experimental determination of added mass during vibration of stiff and elastic body in liquid. |
