The Centre National de la Recherche Scientifique (CNRS) (National Centre for Scientific Research) is a government-funded research organisation under the administrative authority of French Ministry in charge of research. CNRS is the main fundamental research organisation in Europe and is largely involved in national, European, and international projects covering all fields of knowledge. CNRS is organised in more than 1100 laboratories, either intramural or in partnership with universities, other research organisations or industry. In LEMCOTEC project, the research unit involved is CNRS-CORIA, which is a joint laboratory organised between CNRS, the University of Rouen, and INSA of Rouen. CNRS-CORIA is a Mechanical Engineering Lab (185 people) fully devoted to reacting flows.
In the recent years, CORIA has developed a massively-parallel finite-solver able to deal with complex geometries. With this solver, which is able to handle meshes with several billion of elements, very high resolution may be achieved. This resolution will be used in the project to discriminate and optimise injector designs. The very large meshes will also allow studying the integration of the optimised injector in the combustor and in the engine.
