Preparatory subjects: Basics of Mathematical Analysis, Physics, and Hydraulics are required.
In order to assess effective learning, the exam is composed of an oral discussion of about 45 min, focusing 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).
AIM OF THE COURSE
This course aims to integrating knowledge in hydraulics with special reference to:
1. Basic principles of hydrodynamics and related equations
2. Basic principles of energy exchange between flow and hydraulic devices (pumps and turbines), including cavitation assessment
3. Open channel steady flows.
Within the Course of Study in “Environmental and Work-Safety Engineering”, the course is included in the cultural area “advances of engineering related to environmental subjects”.
LEARNING OUTCOMES
At the end of the course, the student will be able to:
1. Calculate hydrodynamic forces
2. Calculate energy production in simplified hydropower schemes and perform cavitation assessments
3. Calculate water surface profiles in steady open channel flows
4. Implement spreadsheets to analyze the proposed problems, with special emphasis on the sensitivity of the solution to the variation of selected parameters
5. Compile short technical reports concerning the proposed problems, including main results in tabular and/or graphical form.
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.
