Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

 

  • Use of turbomachinery for propulsion
  • 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: decomposition in blade-to-blade stream surface and meridional plane, velocity triangles
  • Cascade flows: mass, momentum and energy balances, correlations for compressors and turbines, pitch line design and analysis procedure
  • Meridonal flows: radial equilibrium, design choices, extension of the design and analysis procedure.
  • Real geometry effects: secondary and leakage flows; construction elements
  • Modern design practices: CFD methods for turbomachinery, automatised design, new trends in jet engines, components and design

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, Fluid Mechanics, Aerodynamics, Turbomachinery 

Planned learning activities and teaching methods

Projects are organized which consist in designing a compressor or turbine stage and analysing its performance, using MATLAB or FORTRAN programming.

Mode of delivery (face-to-face ; distance-learning)

8 sessions of 4 hours each are organized during the first part of the academic year.

Recommended or required readings

Course notes are available, as well as a collection of solved exercises. These notes are regularly updated and are distributed during the course.

Assessment methods and criteria

The examination consits in presenting the results of the project.
