Content

Turbomachines play an important role in large parts of our lives. They are used to power almost all modern aircrafts, in power generation or are important components in process industry plants. In processes also higher demands are being placed on efficiency, emissions and performance. In order to meet these challenges a deep understanding of thermodynamics, aerodynamics and structural mechanics of turbomachinery is required.

Building on the knowledge from the course “Flow in Turbomachinery I”, the design process for turbomachinery blading will be run through in this event. In the first few sessions the required basics will be briefly summarized. Further on the students work in small groups to design the blading for a given task. In addition to the aerodynamic design, for which typical calculation methods are used for the preliminary design, a structural-mechanical evaluation of the design is also carried out.

In the final examination the small groups present the results of their design in the form of a presentation. In addition there is an individual examination on theoretical basics.

 

Topics

  • Predesign of a whole turbomachine using the mid-span method
  • Predesign of a turbomachinery blade via Joukowski transformation and the CAD program p- desk
  • Application of 2D CFD calculation methods (MISES: 2D Euler boundary layer method)
  • Application of calculation methods for the static and dynamic strength of the turbomachinery blade
  • Holding a review to present the results
