MJ2430 Thermal Turbomachinery 6.0 credits

Termiska strömningsmaskiner

Thermal turbomachines are widely used in the transport and the energy sector. The operation of modern aircraft would not be possible without thermal turbomachines that feature unprecedented power densities. Most of the world’s electricity is generated in processes where thermal turbomachines play a vital role. Regardless of what fuel may be used as tomorrow's main energy supply thermal turbomachines will most likely be used in the energy transformation process.

The present course provides insight into dedicated areas of thermal turbomachines and aims at giving the background for discussing phenomena of interest on an advanced level.

Course information

Content and learning outcomes

Course contents *

The course intends to give an overview of important aspects in the thermal turbomachines with a focus on applications in the transport sector and in the energy sector

The course aims both at people who want receive more general information about aero and thermodynamic design problems in thermal turbomachines and to people who see themselves utilising thermal turbomachines for different purposes in their future professions.

The course is a continuation of MJ2429 Turbomachinery, and therefore starts at an advanced level. Starting from simple 1D analysis of turbomachine components the view is extended to 2D and 3D analysis

Important aspects such as gas turbine cooling technology, mechanical integrity, materials and system behaviour are elucidated and brought into context.

Critical review of scientific articles will be carried out performed to trigger discussions in an interdisciplinary environment. Calculation exercises will be performed to deepen the understanding of treated phenomena. A study visit to a gas turbine manufacturer or a relevant company is planned.

The course is given in English

If a low number of students are admitted to the course, it can be given in modified form, i.e. mainly as self-studies with guidance when necessary.

Intended learning outcomes *

The course intends to give an overview of important aspects of thermal turbomachines with a focus on applications in the transport sector and in the energy sector

After passing the course, the student should be able to:

1. Explain the 2D and 3D steady flow phenomena in turbomachine components and relate to their design
2. Solve aerothermodynamic problems for 3D design of turbomachinery blades
3. Explain interaction of fluid and structure in thermal turbomachines and relate to the design of included vital components
4. Describe non-stationary flow phenomena in turbomachines
5. Solve problems regarding aeromechanics for turbomachinery blades
6. Describe heat transfer for warm components, material aspects, combustion chamber principles and operational characteristics for thermal turbomachines

Examination and completion

Grading scale *

A, B, C, D, E, FX, F

Examination *

  • LAB1 - Laboratory Exercise, 1.0 credits, Grading scale: P, F
  • TEN2 - Examination, 5.0 credits, Grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Quizzes (non-mandatory) are given weekly and a minimum of 75% correct answers give bonus points at TEN1 if the exam grade awarded is E or higher. Furthermore, if the 6 first of in total 7 quizzes are passed with at least 75% correct answers, grade E will be given for intended learning outcomes #4 and #6 and the corresponding problems in the written exam need thereby not be answered. Expired examination items will be examined through supplementary tasks or complementary assignments during three years after expiration. Thereafter, the examination items according to the current official course syllabus, must be carried out.

Other requirements for final grade *

Written examination. 

Opportunity to complete the requirements via supplementary examination
