Description du projet
Des outils de simulation améliorés pour s’assurer que les nouveaux moteurs ne se laissent pas malmener par les turbulences
Étant donné que les turbines à gaz jouent un rôle crucial dans l’aviation, il est très important d’améliorer leur efficacité et de réduire les émissions qui y sont associées. De nouvelles turbines à gaz à grande vitesse promettent d’apporter une aide précieuse pour atteindre ces objectifs, les simulations permettant de développer des conceptions optimisées. L’écoulement hautement turbulent reste encore un peu délicat à simuler avec précision, mais il revêt une importance critique pour la sécurité et les performances des nouveaux modèles, sans parler des réductions du bruit. Le projet AEROSIMULAT, financé par l’UE, utilisera des méthodes et des outils numériques avancés afin de développer des simulations plus efficaces et précises. Le code source ouvert permettra de propulser des turbines à gaz aérospatiales durables vers de nouveaux horizons.
Objectif
The main goal of this project is to perform efficient and accurate simulations of the turbulent compressible flow and generated noise on the new high-speed gas turbines at operation conditions, with the aim of supporting engineers in the design of efficient engines and effective noise reduction solutions. The main difficulty is to correctly simulate, in an acceptable wall- clock time, high Reynolds and high Mach numbers turbulent flows with important regions of separation and the different length scales and amplitudes among the acoustic and the flow fields.
In this project we propose to tackle these problems by introducing high-order Galerkin methods and a skin friction boundary condition technique extended to compressible flows. Both techniques demonstrated impressive performance results on a different context. Given the fellow’s expertise in compressible flows, and her Third Country host’s expertise in high-order Galerkin methods, we are in a unique position to advance in the solution of this problem. A high performance computing simulation tool developed at the host institution will be used and developed as open source within this project. To go one step further within this interdisciplinary subject, we will establish a close collaboration with CTA, a company in the host country specialized in testing aerospace materials, where the fellow will spend one month of research. During this visit, the simulation results of their turbine prototypes will be analyzed and will be validated against their experimental data.
The fellow will extend her network in the scientific and industrial communities. She will gain new managerial skills and a scientific maturity that will open her doors to obtain a strong research position in Europe. The host and the Third Country host supervisors will also benefit from the advances of this promising collaboration. The obtained results are expected to lead to further research and enhance the prospects of new projects.
