Schedule
Units courses prerequisite and corequisite
Prerequisite or corequisite units are presented within each program
Learning unit contents
- Historical perspectives, basic equations and principles of hydraulic machines.
- Pumps and blowers: hydraulic, manometric and theoretical heights, losses, energetic balances, characteristic curves, centrifugal and axial machines, axial thrust, similarity laws, trimming, interaction of a pump and a system, regulation.
- Hydraulic turbines: energetic balances, Francis, Pelton, Kaplan and bulb turbines, characteristic curves, similarity laws, regulation, wind turbines.
- Cavitation.
- Historical perspectives, principles of compressible flow turbomachines.
- Thermodynamics of compressible flows, similarity laws.
- Compressors : energetic balances, part load.
- Turbines : energetic balances, part load, partial admission, vapour with humidity, load regulation, combined production, gas turbine cooling
Learning outcomes of the learning unit
To understand how turbomachines work, how they can be used in relation to their environment.
Prerequisite knowledge and skills
Thermodynamics, fluid mechanics.
Planned learning activities and teaching methods
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.
Mode of delivery (face-to-face ; distance-learning)
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.
Recommended or required readings
Course notes are available, as well as a collection of solved exercises.
Assessment methods and criteria
An oral examination on the theory and a written examination on the exercises are organized in January (hydraulic part) and in June (compressible part).
