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 is tailored as continuation course for  MJ2429 Fluid Machinery, and therefore starts on an advanced level. Starting from simple 1D analysis of turbomachine components the view is extended to 2D and 3D aspects.

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

Critical reviews of scientific articles will be performed to trigger discussions in an interdisciplinary environment. Calculation exercises will be performed to deepen the understanding of treated phenomena. A study visit is foreseen to a major gas turbine manufacturer.

The course is given in English

Intended learning outcomes *

The course aims at giving an overview of dedicated aspects in thermal turbomachinery. It will focus on applications in the transport sector (aero engines, gas turbines for ship and train propulsion) and the energy sector (steam and gas turbines for power generation).

After completing the course the student will be able to

  • Explain the 2D and 3D steady flow phenomena in turbomachine components
  • Understand the unsteady flow phenomena in turbomachines
  • Understand the major turbomachinery blade design philosophies
  • Perform simple aerodynamic designs
  • Explain the interaction of fluid and structure
  • Understand basic aeromechanical design aspects
  • Perform preliminary calculations of mechanical integrity
  • Understand gas turbine combustor principles and challenges
  • Discuss cooling technologies
  • Choose appropriate materials for turbomachinery applications
  • Understand operational aspects of thermal turbomachines
  • Discuss the content of a scientific article on an advanced level
  • Discuss technically today’s and tomorrow’s challenges related to thermal turbomachines
