Turbine Aero Thermal External Flows

Objective



The overall objectives of the Turbine Aero-Thermal External Flows project are to understand the complex aero-thermal phenomena generated in turbines, to build the associated data bases and to facilitate the validation of improved Computational Fluid Dynamics (CFD) methods. This information is urgently needed for aero-engine and gas turbine companies to improve turbine performance, life and weight and therefore to maintain or increase their competitiveness.

The work programme has been sub-divided in four complementary tasks which form all together a project dealing with the most important turbine external aero-thermal aspects:
- Temperature distortion and interaction effects in turbines;
- Aero-thermal performance of HP turbines;
- Fundamental film cooling studies;
- CFD calculations.

Therefore, 3D detailed experimental studies of unsteady aerodynamics and heat transfer in three full scale 1.5 stage turbines will include the investigations of: the temperature distortion at the turbine entry, the aerodynamic clocking effect, the performance of different types of cooling and the aerodynamic operation of HP/IP and HP/LP interfaces. In parallel to these 3D investigations, some fundamental film cooling studies will be carried out.

Finally, advanced CFD methods as well as industrial tools will also be developed, adapted and tested against the experimental results. All these activities take benefit from previous works performed and facilities developed in the European framework. Nearly all the European aircraft engine manufacturers, two important gas turbine producers and the best available research centres and universities in the turbine domain, are involved in the project to form an European platform being able to carry out the work programme BE97-4440.
