"Stationary models deal with flows that generally do not change over time explained Philippe Villedieu, researcher at the Aerodynamics and Energetics Modeling Department (DMAE) at Onera in Toulouse. Now, during the ignition phase the flows and chemical reactions change very quickly, they aren't stationary at all
The use of plasmas for aerodynamics and combustion has gained growing interest in the past 20 years, and a whole scientific community is now dedicated to this field of research. The content of this special issue reflects the diversity of the applications and of the physical conditions where plasmas are applied: from the subsonic to the supersonic regime, from combustion chambers to external aerodynamics, and from thermal plasmas to cold plasmas
Among other things, this is what the Chimère method, which allows the modeling of flow areas using multiple overlapping and mobile mesh grids, enables us to do. ONERA's expertise in this area was recognized at beginning of 2012, at the conclusion of the Aitec research project, which was dedicated to the non- stationary analysis of turbomachinery in aerodynamics and acoustics
