In the framework of reducing energy losses and of improving eco-efficiency, the Lumiere project aims to better understand and model the mechanisms governing the mixed lubrication regime with the objective of a more accurate estimate of the lifetime and friction losses of the lubricated components. Among the many facets of this problem, the impact of wear particles and their interactions with the lubricating fluid and the surfaces will be more particularly studied: by in-situ observations on dedicated test benches and by the method of discrete elements (DEM) coupled with a lubrication model. The results will then be integrated into a multiscale tool allowing simulations at the component level. The work will be carried out by the Pprime Institute, specialized in the study and simulation of lubrication in collaboration with the LaMCoS, recognized for its skills in the experimental study of tribology and the LMGC, expert in the simulation of contact and wear by DEM.
