Steady and Unsteady Flows in Compressors and Turbines


The area of steady and unsteady flows in compressors and turbines covers all the department's research activities in the field of:

  • Active and passive flow control
  • Detailed investigation of loss reduction
  • Analysis of flow instabilities
  • Optimization of air sealing in high pressure turbines
  • Evaluation of multi-row blade concepts to increase the working range

The experimental investigations are carried out at low speed and high speed test facilities.

  • Current research projects
  • Completed research projects
