The results obtained for the test cases proposed with the software demonstrators NXO and AGHORA confirmed that ONERA is a global leader in the research and development of high-order precise methods for Computational FluidMechanics. Moreover, during the AIAA conference, ONERA presented its state of the art and its main fundamental research activities during a guest session which brought together the leading research and industrial centres of the European and American aeronautical sector
To take all of these phenomena into consideration, ONERA is developing models coupling fluidmechanics and solid mechanics... In numerical simulations of aircraft, fluidmechanics specialists model the motion of air around the wings or in the engines, and structural mechanics researchers analyze the behaviour of the mechanical parts
Taking into account the main missions of ONERA, the activity of this department leans heavily towards the complex facilities and experimental fluidmechanic apparatus especially those challenging ONERA's scientific competences. Turbine test bench- design by Wind Tunnel Division teams
The more complex the shapes are, the more complicated and time consuming to solve the fluidmechanics problems become. The presence of technological effects and innovating technologies in sizes that are much smaller than the characteristic dimensions of the general flow make the modeling even more difficult
Understanding of the physical phenomena of fluidmechanics / fluid-structure interactions. Diagnostic of flows and advanced modelling (turbulence, transition, etc
European directives issued by the Advisory Council for Aeronautics Research in Europe[ Acare] set the bar very high in terms of reducing polluting emissions in engine output: reductions of 50 % for CO2 and 80 % for nitrogen oxides (NOx) by 2020. Predicting these emissions is extremely complex, partly because the production mechanisms involve various scientific disciplines: chemistry, thermodynamics, fluidmechanics, etc
He created a research department at the Ministry, stimulated aeronautics research in universities and founded the fluidmechanics institutes, including the in Lille in 1930, which would later join ONERA. He launched the study of many military aircraft prototypes and developed supercharged engines and air weapons
It is a complex phenomenon, occurring where several disciplines meet- aerothermics, fluidmechanics, chemistry, mass and heat transfer, etc. The micro-droplets of fuel that constitute the mist contain hundreds of different types of chemicals, evaporating at different speeds and different temperatures
ANDHEO engineers, in association with ONERA's researchers, initially set up a coupled platform between the Fluent software (fluidmechanics) and the Zset-Zebulon software (co- developed by ONERA) for the structure part and heat transfers in solids. The tool enabling this strong coupling is the OpenPalm library, an open source tool co- developed by Cerfacs* and ONERA for highly customized couplings
