Grey Area Mitigation for Hybrid RANS-LES Methods (Go4Hybrid)
Date du début: 1 oct. 2013, Date de fin: 30 sept. 2015,
The aeronautical industry lacks confidence in the accuracy of computational fluid dynamics (CFD) in areas of highly non-linear, unsteady flows close to the flight envelope borders, which demands advanced approaches and methods. The family of Hybrid RANS-LES Methods (HRLM) is the best candidate for the next generation of CFD methods for increased fidelity at industrially-feasible expense. While HRL ...

Manipulation of Reynolds Stress for Separation Control and Drag Reduction (MARS)
Date du début: 1 oct. 2010, Date de fin: 31 mars 2014,
"Reynolds stress is the most important quantity affecting the mean flow as it is responsible for a major part of the momentum transfer in the wall bounded turbulent flow. It has a direct relevance to both skin friction and flow separation. Manipulation of the Reynolds stress can directly lead to changes in the viscous stress at the wall so as to effectively control the flow for effective flow cont ...

Computational Aero-acoustic Analysis of Low-noise Airframe Devices with the Aid of Stochastic Method (CALAS)
Date du début: 15 juin 2012, Date de fin: 14 mars 2014,
"The CALAS project addresses, by means of computational aero-acoustic (CAA) analysis, low-noise airframe concepts (CfP topic No: JTI-CS-2011-3-GRA-02-018), including a wing-section with and without a side-edge fence (in WP 1) and a landing-gear system with and without low-noise treatments (in WP 2). The main purpose of the project is to evaluate the baseline and other provided low-noise configurat ...

Advanced Turbulence Simulation for Aerodynamic Application Challenges (ATAAC)
Date du début: 1 avr. 2009, Date de fin: 30 juin 2012,
"The ATAAC project aims at improvements to Computational Fluid Dynamics (CFD) methods for aerodynamic flows used in today’s aeronautical industry. The accuracy of these is limited by insufficient capabilities of the turbulence modelling / simulation approaches available, especially at the high Reynolds numbers typical of real-life flows. As LES will not be affordable for such flows in the next 4 d ...

"Prospecting and promoting scientific cooperation between Europe and China in the field of multiphysics modeling, simulation, experimentation and design methods in aeronautics" (AEROCHINA2)
Date du début: 1 oct. 2007, Date de fin: 31 déc. 2009,
"The aim of the AEROCHINA2 Coordination Support Action (CSA) is to foster the cooperation between a number of industry, university and research organizations in the aeronautics sector in Europe and China in the field of multi-physics modelling, computer simulation and code validation, experimental testing and design methods for the solution of multi-physics problems of interest to the aeronautic s ...
