Within the framework of a consortium including industrial companies and academic institutes, a lattice Boltzmann solver, called LaBS, is currently developed for CFD applications. The software parallel architecture and the physical models used in LaBS are described. The turbulence modeling is based on Large Eddy Simulation approach. For industrial configurations, a wall model is added to take into account near-wall turbulence effects. A dedicated GUI is used for model setup and the post-processing has been automatized using a toolbox based on Paraview scripts.
Industrial results on different application fields are presented : drag calculation, air flow through heat exchangers with rotating fan and wall pressure fluctuation simulations. In the field on internal flows, the example of the simulation of broadband noise generated by a muffler of an exhaust line is shown and a limitation of our current model is highlighted.

INGENIEURS DE L'AUTO SE DIGITALISE

 

 

La revue Ingénieurs de l’Auto est maintenant diffusée en print et on line. Une grande première pour la SIA avec ce numéro 865, disponible au format numérique.

Cette version digitale sera, à chaque numéro, réservée aux membres de la SIA abonnés.

Exceptionnellement pour ce premier numéro on line, et en lien avec la situation de confinement et de télétravail de beaucoup d’ingénieurs de notre industrie, la version digitale du numéro de Mai est accessible à tous.
