Knowledges in "Hydraulics"" are required

The course is divided into two modules: “Hydropower plants” and “Hydraulic Transient”.
The “Hydropower Plants” module aims to provide the basic elements for understanding the system main types operation and the practical tools required for the calculation of the energy production of different kinds/size of plants. The “Hydraulic Transient” module aims to provide the basic concepts related to the unsteady flow phenomenology in pressurized system and its mathematical modeling. The student must also acquire the ability to perform hydraulic tests in unsteady flow conditions for some typical plants (hydroelectric and pumping plants).

“Hydropower plants” (Professor P. Espa)
• Italian hydropower production
• Main hydropower plants in the world
• Determination of a tank capacity and management of flows settled for the allocated capacity
• Exploitation of river basin hydroelectric purposes, hydrodynamic curve
• Hydraulic turbines
• Dams and relative complementary works
• The concept of the environmental impact of hydroelectric plants and the measures to contain it

“Hydraulic Transients” (Professor C. Ciaponi)
• Introduction: general information about the unsteady flow phenomena in hydropower plants and in pumping systems
• Elastic and inelastic approach with the related equations
• Mass oscillation: phenomenon description, equations, analytical and numerical solution
• Water hammer: phenomenon description; equations; numerical solution with the method of characteristics, analysis of the main boundary conditions, introduction to water hammer problems associated with the cavitation phenomenon
• Quick methods for the calculation of water hammer: abrupt and slow closure; Allievi and Michaud formulas.
• Water hammer attenuation: air chambers (design and verification)

Lessons (hours per year in the classroom): 34
Exercises (hours per year in the classroom): 18

Teachers will give documentation on the topics covered in the course and they will indicate proper web sites.
The lesson slides and exercises solution of "Hydraulic Transients" module are available on KIRO Platform.

The “Hydropower plants” module requires an oral test while the “Hydraulic Transients ” module requires a written test. The average of the two votes (if both equal or greater than 18/30) will be the final vote of the course. The positive result of one of the two tests, if accepted by the student, will be used for the final result even for subsequent exam sessions, once the second test will be passed.
