AITEB — An european research project on aero-thermodynamics of turbine endwalls and blades

Abstract

The paper delivers an overview on the European research project AITEB -Aerothermal Investigations on Turbine Endwalls and Blades, which started in year 2000 in the course of the 5. Framework Programme (GROWTH). The aim is to submit an integrated technology and design tool package for the advanced, aerothermal highly loaded design of turbines, especially:• Experimental/numerical investigation on heat transfer and fdm-cooling in separated flow for highly loaded blades including advanced trailing edge cooling • Heat transfer/improved cooling of turbine endwalls: Experimental/numerical work on cooling of turbine endwalls, shrouds and recessed blade tips. • Optimised CFD-process (drawing-grid-modelling-postprocessing-risk assessment) in order to derive the "best practice" to use CFD as a time effective tool. After most of the project life, an overview on the project is delivered. Experimental results of test series at various test sites are compared to numerical simulations of the industrial and university partners.

Development and assessment of a coupled strategy for conjugate heat transfer with Large Eddy Simulation: Application to a cooled turbine blade

“…The T120 cascades were designed by Rolls Royce Deutschland for the European project AITEB (Haselbach and Schiffer, 2007) The film cooling device of the T120D blade is composed of three jet rows located on the pressure side in the region of the main flow separation (Fig. 5).…”
