- Steam turbine configurations.
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.
This course contributes to the learning outcomes I.1, I.2, II.1, III.1, III.2, IV.1, IV.3, IV.4, VI.1, VI.2, VII.2 of the MSc in mechanical engineering.
Prerequisite knowledge and skills
Thermodynamics and dynamics of compressible fluids
Planned learning activities and teaching methods
Mode of delivery (face to face, distance learning, hybrid learning)
Face-to-face course
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.
Exam(s) in session
Any session
- In-person
written exam ( open-ended questions ) AND oral exam
Written work / report
Additional information:
The evaluation consists of a lab report, a written exercise exam and an oral exam on the theory. Each will contribute 1/3 to the final grade.
Work placement(s)
Organizational remarks
The course will be dispensed in 2 hour sessions each week, complemented by 30' Q&A sessions on theory and exercises. A forum will be made available for both theory and exercises.
