HOME GROUP SECTORS PROFESSIONS CAREERS NEWS CONTACT Aeronautics & Space The aeronautics and space sectors are particularly complex and demanding sectors of activity which have undergone profound changes for several years and are facing major usage, technological and commercial challenges. For the sector: optimization of structures, new modes of propulsion, emergence of competing state powers, reduction of the carbon footprint and digitization. For the space industry: new reusable space launchers, emergence of disruptive competing players, satellite constellations, etc. Our expertise of more than 15 years, our know-how, the excellence of our teams and our in- depth knowledge of the sector position INGELIANCE as a reference partner with the largest industrial players in aeronautics and space both in the civil fields. than military.

HOME GROUP SECTORS PROFESSIONS CAREERS NEWS CONTACT Our expertise: Combustion phenomena! Combustion phenomena are very polluting and occur daily in many sectors: industry, transport, etc. To reduce the environmental impact of these phenomena, it is necessary to optimize the combustion chambers so as to improve their efficiency or to reduce the use of certain polluting reaction products such as NOx for example. The modeling of these phenomena is very complex. Beyond the aerothermal model (which corresponds to the fluid flow), it is necessary to associate with it chemical models of expected reactions. Depending on the desired precision, a chemical reaction can thus involve several tens of products / reagents and several hundreds of reactions. The computation time can then be very long, even when using meso-computing centers. In order to achieve a satisfactory compromise between precision and calculation time, it will be necessary to use advanced methods (remeshing, flame thickening, tabulated chemistry, reduction in the number of reactions). As part of his end-of-studies internship within the calculation team of INGELIANCE in Bordeaux, Nicolas DELORT is working on the modeling methods of diffusion flames (without premixing ) in so-called complex chemistry. This method makes it possible to produce more precise results, using the YALES2 calculation code developed at Coria. The video above shows you how to start a flame in a test chamber . The calculations were carried out at CCRT, the CEA's computing center. GROUP SECTORS PROFESSIONS CAREERS CONTACT LEGAL NOTICE FRENCH © INGELIANCE 2021
