Preparatory subjects: Basics of Mathematical Analysis, Physics, and Hydraulics are required.
Oral exam of about 45 min, focused on the technical reports compiled by the student.
These reports concern:
- Exercises provided by the professor (reporting a summary of the computation technique and of the obtained result, in graphical and/or tabular form)
- Insights concerning specific topics related to the course, but not adequately developed in the classroom, proposed by the professor or by the students (the professor usually suggests one or two bibliographic references)
To compile the technical reports, teamwork is warmly recommended: groups of 3-5 students are usually formed at the starting of the course. The complete set currently amounts to 10 technical reports, with specific subjects and supporting information available on the e-learning platform.
The final rating is in thirtieths (min 18, max 30).
Cultural area: advances of engineering related to environmental subjects.
Knowledge and understanding: basic principles of hydrodynamics and related equations; basic principles of energy exchange between flow and hydraulic devices (pumps and turbines), including cavitation assessment; open channel steady flows.
Applying knowledge and understanding: calculate hydrodynamic forces; calculate energy production in simplified hydropower schemes and perform cavitation assessments; calculate water surface profiles in steady open channel flows.
The course is subdivided into three main blocks, HYDRODYNAMICS, ENERGY EXCHANGE BETWEEN FLOW AND HYDRAULIC DEVICES (PUMPS & TURBINES), and STEADY OPEN CHANNEL FLOWS, respectively. Related contents are detailed in the following. The hours of classroom lesson concerning the specific subjects are reported in brackets. The overall number of hours is 48.
First module of the course – HYDRODYNAMICS [16]:
- Stress tensor [4],
- Viscosity, Newtonian and non-Newtonian fluids [2],
- Equations of dynamic equilibrium in differential form, Euler equations, Navier-Stokes equations, dynamic effects of turbulence and Reynolds equations (essentials) [4],
- Equations of dynamic equilibrium in integral form, computation of hydrodynamic forces [6].
Second module of the course – ENERGY EXCHANGE BETWEEN FLOW AND HYDRAULIC DEVICES (PUMPS & TURBINES) [14]:
- Hydropower and hydraulic turbines, energy generation of a hydropower scheme (essentials) [6],
- Cavitation assessment in centrifugal pumps and reaction turbines [8].
Third module of the course – STEADY OPEN CHANNEL FLOWS [18]:
- Uniform flow for general cross-section and roughness distribution [2],
