Course description for academic year 2020/2021
Contents and structure
Hydraulics is the section of fluid mechanics which describes production, transmission and conversion of energy during mutual interaction of fluids and mechanisms in motion. This course starts from the deep fundamentals of fluid dynamics accompanied at later stages by an overall description of technical solutions used in machinery. The main objective of the course is to learn basic principles of fluid power generation, transmission and conversion with the use of hydraulic machines and supplementary passive equipment.
- Introduction, nomenclature and main principles
- Selected chapters of fluid dynamics: flow regimes, velocity profiles, pressure drop, Bernoulli equation
- Hydraulic fluids: types, properties and selection
- Basic theory of hydraulic machines: forces and torques, displacement, mass and momentum loss
- Positive displacement pumps and motors: types, design, operation and efficiency
- Rotodynamic machines: types, design, Euler equation and efficiency
- Cavitation: fundamentals, NPSH (net positive suction head)
- Passive hydraulic equipment: valves, filters and tanks
- Hydraulic accumulators: fundamentals, types, selection
- Hydraulic schemes: standardized symbolics and machine logics
- Thermal comfort of hydraulic loops
- Mechanical analysis of selected components
- Overview over numerical tools in hydraulics
At the completion of the course, students should be able to accumulate following
- basic aspects of the power conversion in hydraulic machines
- key components of a hydraulic scheme
- details of a hydraulic system operation
- selection of main components of a hydraulic rig
- quantitative estimation of the main operating parameters (forces, torques, flow rates, efficiencies)
- calculation of mass and momentum loss in hydraulic machines
- practical competence in the use of hydraulic equipment
- Writing of technical reports, group work, statistical analysis, analysis of measurement errors.
