Context / Contexte
With the trend to reduce weight and increase stage loading of aeroengine components, flutter predictions have become a key issue in turbomachinery design. Available knowledge and state of the art predictions are quite fair regarding isolated blade flutter (http://www.cerfacs.fr/4-26774-Aeroelasticity-and-flutter-prediction.php). However, the picture is rather different when the surroundings of the blade are included: unsteady wake passing from upstream rows and potential effects from downstream blades can significantly modify the flutter behavior.In this context, the FUTURE FP7 European project (http://www.future-project.eu/) aims at tackling the problem of flutter in a multi-blade rows environment. To this end, innovative experiments are being set up at several European research laboratories (KTH of Stockholm, EPFL of Lausanne, TU Darmstadt) and new numerical methods are developed, the final objective being a deepened understanding of the flutter phenomenon.
Description / Description
The work will consist in the numerical simulation and analysis of the blade aerodynamic forced response.The first objective is to validate the harmonic balance method developed at CERFACS, which is implemented in the elsA code (http://pantar.cerfacs.fr/4-25716-Software.php). This will be done through comparisons with the experimental data generated during the FUTURE project.
The second objective is to analyze the results so as to provide physical insight into the influence of rows interactions on the aeroelastic behaviour of compressors and turbines.
The successful candidate is expected to publish in international journals. This position will be an excellent opportunity to meet and interact with renowned research laboratories and engine manufacturers across Europe (Snecma, Rolls-Royce, Volvo Aero ...), and with Turboméca in particular.
Previous CFD members of CERFACS are found everywhere in industry and academic positions (see http://pantar.cerfacs.fr/4-26339-Ex-members-of-the-CFD-Team.php).
