Obiettivo Objectives and content The project aims at providing a greater understanding of unsteady flow phenomena associated with turbine rotor-stator interaction and improved turbulence models that can be used in industrial codes for turbomachinery design. The project represents the first major concerted effort in this area and is seen by the industrial partners as a vital element in developing improved turbine design methods essential to ensuring future competitive products. Three major tasks are planned: - Examination of non-isotropic turbulence models and simulation techniques for prediction of unsteady wake flow features associated to wakes and wake-blade interactions. This Task is trusted to 4 different University research groups. Non-linear 2 equation models, linear and non-linear Reynolds Stress Transport models and Large Eddy Simulation techniques will be examined and tested against experiment data provided by Task 2. Task 1 partners will make recommendations to Task 3 partners as to which models appear to be the most promising and the most suitable for unsteady turbine flow calculations. - Experimental test cases for assessment of turbulence models. Three turbomachinery laboratories are in charge of establishing 3 benchmark test cases, featuring strong unsteady flow effects: (I) unsteady turbine blade wake flows at high subsonic and transonic downstream velocities; (2) effect of coolant flow ejection on unsteady blade wake flow characteristics at low speed; (3) wake-blade interference simulated with a moving bar system in a low speed linear cascade. Emphasis is put on measuring the time varying wake and boundary layer characteristics. The experimental partners will provide the modelling partners with well documented data sets for code validation. - Unsteady 2-D and 3-D blade row arid stage calculations. This task is jointly undertaken by all industrial companies and one University group. A 3-step approach is adopted: . determination of the major physical effects and the relative importance of interaction effects comparing full rotor-stator analysis with simple blade row analysis with incoming upstream wake and potential effects; . experimenting advanced turbulence models proposed under Task 1 in a complex blade row interaction environment; . compare steady and unsteady 3-D blade row and stage calculations to assess the potential impact of the combined effect of unsteady calculations and advanced turbulence on future blade design.
