|
|
| Course objective : | To understand how turbomachines work, how they can be used in relation to their environment. |
|
| Prerequisites : | Thermodynamics, fluid mechanics. |
|
| Workshops : | Two laboratory sessions (2 hours each) are organized, devoted to the test of a centrifugal, a Pelton turbine, a gas turbine, the acquisition and analysis of pressure, flow, torque measurements, and the assessment of the
performances of those machines. |
|
| Organization : | This course is organized throughout the academic year, by 2 hour sessions, at a rate of about 30 hours of theory and 20 hours of exercises. |
|
| Written notes : | Course notes are available, as well as a collection of solved exercises. |
|
| Assessment : | An oral examination on the theory and a written examination on the exercises are organized in January (hydraulic part) and in June (compressible part). |
