Prerequisite or corequisite units are presented within each program
Learning unit contents
Theory
- Use and classification of turbomachinery
- Derivation of the general equations, basic principles, control volumes, energy transfer and irreversibilities, absolute and relative frames, Euler equation of turbomachinery
- Thermodynamic performances, efficiencies, operating maps and similarity
- Quasi-3D design and analysis method for axial machines: decomposition in blade-to-blade stream surface and meridional plane, velocity triangles, cascade flows; pitch line design and analysis procedure
- Meridonal flows: radial equilibrium, design choices, extension of the design and analysis procedure.
- Real effects: secondary and leakage flows; operation at off-design, construction elements
- Modern design practices: CFD methods for turbomachinery, automatised design,
- Recent trends in propulsion and jet engines, and their impact on components and design
- Pre-design of an axial machine
- estimation of the operating curves of the aforementioned machine
- CFD analysis of a turbomachinery passage and analysis of secondary flow
Learning outcomes of the learning unit
To understand the physics of the flow in turbomachines.
To understand the methods used for aerodynamic design of turbomachines.
Prerequisite knowledge and skills
Thermodynamics and dynamics of compressible fluids.
Planned learning activities and teaching methods
A number of assignments are given along the course, consisting of the preliminary design of a multistage compressor or turbine, the analysis of the off-design performance using quasi-1D methods; CFD analysis of passages
Mode of delivery (face to face, distance learning, hybrid learning)
12 sessions of 3 hours each are organized during the first part of the academic year.
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. If students wish to assist remotely, the course will be transmitted live via the virtual class room on e-campus. The course is then 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 online. These notes are regularly updated and distributed via the e-campus page of the course, which also hosts the virtual class room and fora for questions etc. Further material is referenced in the course, and will be proposed to the students in function of their interests.
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 course is evaluated on the basis of the project results, which are discussed in an oral exam.
