Project Title:

  Innovative Numerical Calculation of the Transonic Flow Through High-loaded Turbines


Project Start:

  March 2008; Project End: February 2011


Project Partners:

   MTU Aero Engines GmbH
   Springer und Pieringer EDV OEG
   Graz University of Technology

Project Coordiantor:

  Graz University of Technology


Project Applicants / Contact:

   Ao.Univ.-Prof. Dipl.-Ing. Dr.techn. Wolfgang Sanz
   Dipl.-Ing. Maria Kelterer


Objective:

  An aero engine manufacturer, a small enterprise and a university institute will work
  together on the improved CFD calculation of transonic turbine flows with emphasis on the
  complex flow phenomena laminar-to-turbulent transition and relaminarization not yet
  satisfactorily solved in modern CFD solvers. The new approach will be applied to intermediate
  turbine duct design thus leading to a short term benefit for future aero engine design.
