The Cerfacs will participate in the French HPC competence centre.

superadmin |  17 April 2020

The European Commission, via a EuroHPC call for projects, has asked each of the member states to create a National HPC Competence Centre, which will be its sole interlocutor, both to express the needs of users with regard to these new technologies and to accompany them in their implementation. Teratec, Cerfacs and Genci presented their candidature as French HPC Competence Centre which was accepted by the commission. The starting date of the Competence Centre is set for 1 September 2020.Read more

Results exhibit a very complex double flame structure with diffusion and premixed flames, as well as group and individual droplet burning. Monodisperse two-phase counterflow flames are also computed to help analysing the polydisperse flame, and confirm the strong link between droplet diameter and flame regime. For small droplet diameters, the flame has the same structure than a gaseous flame at a different equivalence ratio, and the flame power increases with the droplet size. For larger droplets, the premixed mode becomes dominant and the flame power exceeds the maximum gaseous diffusion flame power.}, keywords = {ARC, Counter-flow diffusion, Spray, Droplet}}

Starting from a given velocity distribution corresponding to an intended flow recirculation, the athermal counterpart of the Euler equations are solved to obtain a consistent density field. The present initialization is assessed on a standard lattice Boltzmann solver based on the D2Q9 lattice. Compared to the usual isentropic initialization, a much lower spurious relaxation toward the targeted solution is observed, which is due to the spatial resolution rather than approximated macroscopic quantities. The amplitude of the spurious waves can be further reduced by including an off-equilibrium part in the initial distribution functions. }, keywords = {lattice Boltzmann method}, url = {https://journals.aps.org/pre/abstract/10.1103/PhysRevE.101.043306}}
