|
| Course objective : | To understand how the hydraulic machines work, how they are sized and how they can be used in relation to their environment. |
|
| Prerequisites : | Hydraulics and fluid mechanics. |
|
| Workshops : | Two laboratory sessions (2 hours each) are organized, devoted to the test of a centrifugal pump and a positive-displacement pump, the test of a Pelton turbine, the acquisition and analysis of pressure, flow, torque measurements, and the assessment of the
performances of the machines. |
|
| Organization : | This course is organized throughout the second half of the academic year, by 4 hour sessions, at a rate of about 35 hours of theory and 15 hours of exercises. |
|
| Written notes : | Course notes are available, as well as a collection of solved exercises. These notes are regularly updated and are distributed during the course. |
|
| Assessment : | An oral examination on the theory and a written examination on the exercises are organized in June (1st session) and September (2nd session). |
