Units courses prerequisite and corequisite
Prerequisite or corequisite units are presented within each program
Learning unit contents
- Classification and use of turbomachines
- Recap on compressible fluid flow: equations of state, total conditions, Fanno and Rayleigh flows, choking, shocks, flow in the converging-diverging nozzle;
- Recap of turbomachinery theory and extension to compressible fluids: force and energy transfer in relative frames; Euler's equation of turbomachinery; velocity triangles; similarity, h-s diagrams;
- Compressors: operation and components, h-s diagrams, efficiencies, characteristic curves and operating limits, similarity, corrected conditions
- Turbines : operation and components, h-s diagrams, efficiencies, characteristic curves and operating limits, similarity, corrected conditions
- Turbocharging: configurations et cycle thermodynamique globale, turbocharger components operation and matching
- Jet engines : ram effect, turbojet, civil and military turbofans, afterburning, recent evolutions
- Steam turbines and power generation plants
Learning outcomes of the learning unit
The course objectives are that the student
- understands the operation of the turbomachine at the component level at the nominal point of operation and at off-design;
- understands the physical phenomena that limit the operating range of the components;
- can determine the thermodynamic conditions inside the machine on the h-s diagram, and reconstruct the corresponding velocity triangles;
- can use the operating maps and compute the corrected operating conditions
- understands the function and operation of turbomachinery components in typical applications including energy production, turbocharging and jet engines;
- can determine the operating point of a component in an industrial environment, a turbocharged engine, a Brayton cycle, a jet engine.
Prerequisite knowledge and skills
Thermodynamics and dynamics of compressible fluids
Planned learning activities and teaching methods
A visit to the turbomachinery labs at the von Karman institute is organized.
Mode of delivery (face to face, distance learning, hybrid learning)
This course is organised during the second quadrimester, with 2h to 2h30 sessions.
Organisational adjustments related to the current health context
The course will be organised such as to allow interaction during the session, whether the student is attending the course physically or virtually.
To this end, the course is elaborated live on the computer, with the aid of a graphical tablet, as a replacement to the blackboard. The result is projected on the screen in the class room, transmitted live via the virtual class room on e-campus. The course is also recorded at the same time and made available on e-campus. At any time, the student can intervene for questions or clarifications, ...
Following the color code
- yellow: Currently, the class room is sufficiently large to accomodate all students. The student can therefore choose whether to attend physically or virtually.
- orange: if needed, the students wishing to attend the course physically will be distributed over two groups, who will follow the course at two different times.
- red: the course is organised in the same way with only virtual attendance
Recommended or required readings
Course notes are available, as well as a collection of exercises will be available in electronic format on the e-campus site of the course. These can still evolve over the quadrimester. Supplementary material is referenced in the text, will be put available in electronic format on the e-campus site if possible, and suggested to the student in function of his/her interest.
Assessment methods and criteria
Below you will find information on the evaluation methods planned for in-person and remote exams as well as those planned for hybrid sessions. Depending on how the health crisis evolves, the chosen method will be communicated to you no later than one month before the start of the exam session.
Any session :
- In-person
written exam ( open-ended questions ) AND oral exam
- Remote
written exam ( open-ended questions ) AND oral exam
- If evaluation in "hybrid"
preferred remote
Additional information:
The evaluation consists of a written exercise exam, which will determine 2/3 of the final grade, and an oral exam on the theory.
